GHSA-7WW3-XVF5-CXWM
Vulnerability from github – Published: 2026-05-05 22:20 – Updated: 2026-05-05 22:20Summary
ciguard's FastAPI Web UI (src/ciguard/web/app.py) does not set HTTP defence-in-depth headers. OWASP ZAP baseline scan flagged 11 alerts: missing Content-Security-Policy (Medium), X-Frame-Options (Medium), Sub-Resource-Integrity on /api/docs (Medium), COOP / COEP / CORP (Low), Permissions-Policy (Low), X-Content-Type-Options (Low).
Threat scenario
For local-only deployment (current intent): minimal — there's no untrusted browser context, no third-party hosting, no auth surface to protect.
For public hosting (PRD Slice 9 GitHub App or hosted dashboard, future): each missing header reduces a defence layer:
- Missing CSP → injected XSS would have no second-line defence (first-line Jinja autoescape remains intact)
- Missing X-Frame-Options → clickjacking against any UI button would be possible
- Missing SRI on jsdelivr-hosted Swagger UI → if jsdelivr were compromised, attacker JS would run in the docs page context
Patch
- New
SecurityHeadersMiddlewareatsrc/ciguard/web/security_headers.pyinjecting: X-Content-Type-Options nosniff, X-Frame-Options DENY, Referrer-Policy no-referrer, Permissions-Policyinterest-cohort=(), Cross-Origin-Opener-Policy same-origin, Cross-Origin-Resource-Policy same-origin, plus per-path CSP with/api/docs+/api/redoccarve-out for cdn.jsdelivr.net (Swagger UI / ReDoc dependency). - COEP intentionally NOT set: would break Swagger UI's cross-origin assets, and ciguard makes no SharedArrayBuffer use that would benefit.
- Registered via
app.add_middleware(SecurityHeadersMiddleware). - 6 regression tests in
tests/test_web.py::TestSecurityHeaders.
Discovery
Found by OWASP ZAP baseline scan during ciguard's first self-conducted pentest cycle, 2026-04-26.
CVSS Scoring
- CVSS v3.1:
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N— 4.3 (Medium per v3.1 thresholds) - CVSS v4.0:

Vulnerability from github – Published: 2022-05-24 19:19 – Updated: 2023-07-07 21:30A missing HTTP header (X-Frame-Options) in Kiwi Syslog Server has left customers vulnerable to click jacking. Clickjacking is an attack that occurs when an attacker uses a transparent iframe in a window to trick a user into clicking on an actionable item, such as a button or link, to another server in which they have an identical webpage. The attacker essentially hijacks the user activity intended for the original server and sends them to the other server. This is an attack on both the user and the server.

GHSA-8398-GMMX-564H
Vulnerability from github – Published: 2026-02-04 19:42 – Updated: 2026-03-25 03:12Impact
A vulnerability in the Python Code node allows authenticated users to break out of the Python sandbox environment and execute code outside the intended security boundary.
Only authenticated users are able to execute code through Task Runners.
This issue affected any deployment in which the following conditions were met:
- Task Runners were enabled using
N8N_RUNNERS_ENABLED=true(default: false) - Python was enabled
N8N_PYTHON_ENABLED=true - Code Node was enabled (default: true)
In case the N8N_RUNNERS_MODE is set to external (default: internal) the sandbox escape is limited to the sidecar container with lower risk for lateral movement. In that case a lower high severity is more appropriate.
Patches
This vulnerability is fixed in version 2.4.8 and later.
Workarounds
If an immediate upgrade cannot be applied, the following hardening steps are recommended:
- Disable the Code Node by adding
n8n-nodes-base.codeto theNODES_EXCLUDEenvironment variable - Prefer external mode for isolation: run Task Runners in external mode so that untrusted task code executes in a separate sidecar container rather than within the main n8n process. This configuration significantly reduces the risk of in-process memory disclosure caused by unsafe buffer allocations.In external mode, a launcher manages Task Runner processes in a dedicated sidecar environment, separate from the primary n8n instance. See the [n8n documentation](https://docs.n8n.io/hosting/configuration/task-runners/) for configuration details and required environment variables.

No mitigation information available for this CWE.
CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs
In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.
CAPEC-107: Cross Site Tracing
Cross Site Tracing (XST) enables an adversary to steal the victim's session cookie and possibly other authentication credentials transmitted in the header of the HTTP request when the victim's browser communicates to a destination system's web server.
CAPEC-127: Directory Indexing
An adversary crafts a request to a target that results in the target listing/indexing the content of a directory as output. One common method of triggering directory contents as output is to construct a request containing a path that terminates in a directory name rather than a file name since many applications are configured to provide a list of the directory's contents when such a request is received. An adversary can use this to explore the directory tree on a target as well as learn the names of files. This can often end up revealing test files, backup files, temporary files, hidden files, configuration files, user accounts, script contents, as well as naming conventions, all of which can be used by an attacker to mount additional attacks.
CAPEC-17: Using Malicious Files
An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
CAPEC-20: Encryption Brute Forcing
An attacker, armed with the cipher text and the encryption algorithm used, performs an exhaustive (brute force) search on the key space to determine the key that decrypts the cipher text to obtain the plaintext.
CAPEC-22: Exploiting Trust in Client
An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
CAPEC-237: Escaping a Sandbox by Calling Code in Another Language
The attacker may submit malicious code of another language to obtain access to privileges that were not intentionally exposed by the sandbox, thus escaping the sandbox. For instance, Java code cannot perform unsafe operations, such as modifying arbitrary memory locations, due to restrictions placed on it by the Byte code Verifier and the JVM. If allowed, Java code can call directly into native C code, which may perform unsafe operations, such as call system calls and modify arbitrary memory locations on their behalf. To provide isolation, Java does not grant untrusted code with unmediated access to native C code. Instead, the sandboxed code is typically allowed to call some subset of the pre-existing native code that is part of standard libraries.
CAPEC-36: Using Unpublished Interfaces or Functionality
An adversary searches for and invokes interfaces or functionality that the target system designers did not intend to be publicly available. If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.
CAPEC-477: Signature Spoofing by Mixing Signed and Unsigned Content
An attacker exploits the underlying complexity of a data structure that allows for both signed and unsigned content, to cause unsigned data to be processed as though it were signed data.
CAPEC-480: Escaping Virtualization
An adversary gains access to an application, service, or device with the privileges of an authorized or privileged user by escaping the confines of a virtualized environment. The adversary is then able to access resources or execute unauthorized code within the host environment, generally with the privileges of the user running the virtualized process. Successfully executing an attack of this type is often the first step in executing more complex attacks.
CAPEC-51: Poison Web Service Registry
SOA and Web Services often use a registry to perform look up, get schema information, and metadata about services. A poisoned registry can redirect (think phishing for servers) the service requester to a malicious service provider, provide incorrect information in schema or metadata, and delete information about service provider interfaces.
CAPEC-57: Utilizing REST's Trust in the System Resource to Obtain Sensitive Data
This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to obtain sensitive data once SSL is terminated.
CAPEC-59: Session Credential Falsification through Prediction
This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
CAPEC-65: Sniff Application Code
An adversary passively sniffs network communications and captures application code bound for an authorized client. Once obtained, they can use it as-is, or through reverse-engineering glean sensitive information or exploit the trust relationship between the client and server. Such code may belong to a dynamic update to the client, a patch being applied to a client component or any such interaction where the client is authorized to communicate with the server.
CAPEC-668: Key Negotiation of Bluetooth Attack (KNOB)
An adversary can exploit a flaw in Bluetooth key negotiation allowing them to decrypt information sent between two devices communicating via Bluetooth. The adversary uses an Adversary in the Middle setup to modify packets sent between the two devices during the authentication process, specifically the entropy bits. Knowledge of the number of entropy bits will allow the attacker to easily decrypt information passing over the line of communication.
CAPEC-74: Manipulating State
The adversary modifies state information maintained by the target software or causes a state transition in hardware. If successful, the target will use this tainted state and execute in an unintended manner.
State management is an important function within a software application. User state maintained by the application can include usernames, payment information, browsing history as well as application-specific contents such as items in a shopping cart. Manipulating user state can be employed by an adversary to elevate privilege, conduct fraudulent transactions or otherwise modify the flow of the application to derive certain benefits.
If there is a hardware logic error in a finite state machine, the adversary can use this to put the system in an undefined state which could cause a denial of service or exposure of secure data.
CAPEC-87: Forceful Browsing
An attacker employs forceful browsing (direct URL entry) to access portions of a website that are otherwise unreachable. Usually, a front controller or similar design pattern is employed to protect access to portions of a web application. Forceful browsing enables an attacker to access information, perform privileged operations and otherwise reach sections of the web application that have been improperly protected.
