Title

React Router: Unauthenticated Denial of Service via Inefficient Route Matching

Summary

React Router is a router for React. In versions 7.0.0 through 7.17.0, the manifest endpoint could be accessed via unauthenticated targeted requests that would put heavy load on the server and slow down response times. This issue is a follow up to CVE-2026-42342, and does not does not impact React Router applications using Declarative Mode (<BrowserRouter>) or Data Mode (createBrowserRouter/<RouterProvider>). This issue has been fixed in version 7.18.0.

Severity

8.7 (High)

CVE-2026-55646 (GCVE-0-2026-55646)

Vulnerability from cvelistv5 – Published: 2026-07-06 19:41 – Updated: 2026-07-06 19:49

Title

vLLM speech-to-text endpoints allocate full upload before enforcing the audio file-size limit

Summary

vLLM is an inference and serving engine for large language models. From 0.22.0 to 0.23.0, the /v1/audio/transcriptions and /v1/audio/translations routes call request.file.read() to fully materialize an uploaded audio file into memory before vLLM checks the documented VLLM_MAX_AUDIO_CLIP_FILESIZE_MB compressed upload size limit (default 25 MB) later in the speech-to-text preprocessing step, so an API caller who can reach those routes can submit an oversized multipart upload and cause vLLM to allocate memory proportional to the uploaded file size before the request is rejected as too large, creating memory pressure or terminating the process depending on deployment resource limits. This issue is fixed in version 0.24.0.

Severity

6.5 (Medium)

CVE-2026-55588 (GCVE-0-2026-55588)

Vulnerability from cvelistv5 – Published: 2026-08-25 20:32 – Updated: 2026-08-27 14:35

Title

ORAS CLI: Cyclic Referrer Graph Can Cause Unbounded Recursion and Resource Consumption

Summary

ORAS (OCI Registry As Storage) is a CLI and library for managing artifacts in OCI registries. In ORAS CLI versions up to and including 1.3.2, the recursive referrer traversal does not track visited descriptors, so a malicious OCI registry that returns a cyclic referrer graph causes unbounded recursion and memory growth. This affects oras discover, whose recursive traversal is enabled by default because the --depth option defaults to 0 (unlimited), as well as the recursive referrer counting used by the oras backup and oras restore workflows. A cyclic graph can be as simple as A referring to B and B referring back to A. A malicious registry can use this to cause a client-side denial of service, exhausting CPU and memory and hanging automation or CI/CD pipelines that run ORAS against untrusted registry metadata. The vulnerability does not extend to code execution, artifact substitution, or integrity bypass. This issue has been fixed in version 1.3.3.

CVE-2026-55531 (GCVE-0-2026-55531)

Vulnerability from cvelistv5 – Published: 2026-08-25 14:33 – Updated: 2026-08-25 16:14

Title

PraisonAI: Unauthenticated unbounded session accumulation in the PraisonAI MCP HTTP server (memory exhaustion; session TTL never enforced)

Summary

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, the MCP HTTP Stream mcp_post handler creates a new _sessions entry for every initialize request but does not call _cleanup_sessions or enforce a maximum. An unauthenticated caller can exhaust memory. The fix invokes cleanup and limits sessions through PRAISONAI_MCP_MAX_SESSIONS. This issue is fixed in version 4.6.58.

Severity

6.5 (Medium)

CVE-2026-55520 (GCVE-0-2026-55520)

Vulnerability from cvelistv5 – Published: 2026-08-28 18:42 – Updated: 2026-08-31 18:54

Title

Protego: Exponential backtracking ReDoS in robots.txt URL wildcard matching

Summary

Protego is a pure-Python robots.txt parser with support for modern conventions. Prior to 0.6.2, protego._urlpattern._URLPattern._prepare_pattern_for_regex translates every asterisk in an Allow or Disallow directive into a lazy regular-expression wildcard, so a directive containing many asterisks creates exponential backtracking. After protego.Protego.parse processes a crafted robots.txt file, protego.Protego.can_fetch can spend an attacker-controlled period matching a near-miss URL and deny service to the crawler. The vulnerable path is src/protego/_urlpattern.py in the _URLPattern match logic. This issue is fixed in version 0.6.2.

Severity

7.1 (High)

CVE-2026-55512 (GCVE-0-2026-55512)

Title

nebula-mesh: Unauthenticated OIDC login endpoint allocates unbounded in-memory state entries without rate limiting

Summary

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. From version 0.2.0 to before version 0.5.0, when OIDC is enabled, GET /ui/oidc/login is reachable without authentication and is registered outside the Web UI rate-limited auth routes. Every request creates a fresh random OIDC state value and stores it in an in-memory map for 10m. Expired states are swept lazily, but there is no rate limit or maximum live-state cap on the allocation path. An unauthenticated remote client can therefore grow OIDC.states for the full state TTL, bounded by request throughput rather than by configured auth rate limits. This issue has been patched in version 0.5.0.

Severity

5.3 (Medium)

Title

Cloudreve: Server crash through image decompression/pixel bomb in thumbnail & avatar decoding (DoS)

Summary

Cloudreve is a self-hosted file management and sharing system. Prior to 4.17.0, the built-in thumbnail and avatar image decoders limit compressed file size but do not limit decoded pixel dimensions, allowing an authenticated user to submit a small PNG, JPEG, or GIF that triggers an unbounded allocation and terminates the Cloudreve process through fatal out-of-memory behavior. This issue is fixed in version 4.17.0.

Severity

6.5 (Medium)

CVE-2026-55450 (GCVE-0-2026-55450)

Vulnerability from cvelistv5 – Published: 2026-06-23 16:17 – Updated: 2026-06-23 17:02

Title

Langflow: Unauthenticated file upload leads to DoS (space exhaustion) and information leak

Summary

Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.1, unauthenticated users can upload any amount of data to the server without any limitations. No need for any prior knowledge, only network access to Langflow. This can lead to space exhaustion on the server. In addition, in the response, the absolute path of the uploaded file is reported to the attacker, which is an information leak that can assist in chaining other primitives. This vulnerability is fixed in 1.9.1.

Severity

9.3 (Critical)

Mitigation

Architecture and Design

Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.

Mitigation

Architecture and Design

Mitigation of resource exhaustion attacks requires that the target system either:
The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
The second solution is simply difficult to effectively institute -- and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
recognizes the attack and denies that user further access for a given amount of time, or
uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.

Mitigation

Architecture and Design

Ensure that protocols have specific limits of scale placed on them.

Mitigation

Implementation

Ensure that all failures in resource allocation place the system into a safe posture.

CAPEC-147: XML Ping of the Death

An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.

CAPEC-227: Sustained Client Engagement

An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.

CAPEC-492: Regular Expression Exponential Blowup

An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
