| CVE-2024-58340 | 1 Langchain | 1 Langchain | 2026-01-21 | N/A | 7.5 HIGH |
| LangChain versions up to and including 0.3.1 contain a regular expression denial-of-service (ReDoS) vulnerability in the MRKLOutputParser.parse() method (libs/langchain/langchain/agents/mrkl/output_parser.py). The parser applies a backtracking-prone regular expression when extracting tool actions from model output. An attacker who can supply or influence the parsed text (for example via prompt injection in downstream applications that pass LLM output directly into MRKLOutputParser.parse()) can trigger excessive CPU consumption by providing a crafted payload, causing significant parsing delays and a denial-of-service condition. | |||||
| CVE-2026-21868 | 1 Flagforge | 1 Flagforge | 2026-01-20 | N/A | 7.5 HIGH |
| Flag Forge is a Capture The Flag (CTF) platform. Versions 2.3.2 and below have a Regular Expression Denial of Service (ReDoS) vulnerability in the user profile API endpoint (/api/user/[username]). The application constructs a regular expression dynamically using unescaped user input (the username parameter). An attacker can exploit this by sending a specially crafted username containing regex meta-characters (e.g., deeply nested groups or quantifiers), causing the MongoDB regex engine to consume excessive CPU resources. This can lead to Denial of Service for other users. The issue is fixed in version 2.3.3. To workaround this issue, implement a Web Application Firewall (WAF) rule to block requests containing regex meta-characters in the URL path. | |||||
| CVE-2026-22809 | 1 Amauri | 1 Tarteaucitronjs | 2026-01-20 | N/A | 4.4 MEDIUM |
| tarteaucitron.js is a compliant and accessible cookie banner. Prior to 1.29.0, a Regular Expression Denial of Service (ReDoS) vulnerability was identified in tarteaucitron.js in the handling of the issuu_id parameter. This vulnerability is fixed in 1.29.0. | |||||
| CVE-2025-25200 | 1 Koajs | 1 Koa | 2026-01-20 | N/A | 7.5 HIGH |
| Koa is expressive middleware for Node.js using ES2017 async functions. Prior to versions 0.21.2, 1.7.1, 2.15.4, and 3.0.0-alpha.3, Koa uses an evil regex to parse the `X-Forwarded-Proto` and `X-Forwarded-Host` HTTP headers. This can be exploited to carry out a Denial-of-Service attack. Versions 0.21.2, 1.7.1, 2.15.4, and 3.0.0-alpha.3 fix the issue. | |||||
| CVE-2025-25290 | 2026-01-16 | N/A | 5.3 MEDIUM | ||
| @octokit/request sends parameterized requests to GitHub’s APIs with sensible defaults in browsers and Node. Starting in version 1.0.0 and prior to versions 9.2.1 and 8.4.1, the regular expression `/<([^>]+)>; rel="deprecation"/` used to match the `link` header in HTTP responses is vulnerable to a ReDoS (Regular Expression Denial of Service) attack. This vulnerability arises due to the unbounded nature of the regex's matching behavior, which can lead to catastrophic backtracking when processing specially crafted input. An attacker could exploit this flaw by sending a malicious `link` header, resulting in excessive CPU usage and potentially causing the server to become unresponsive, impacting service availability. Versions 9.2.1 and 8.4.1 fix the issue. | |||||
| CVE-2025-53539 | 1 Fastapi-guard | 1 Fastapi Guard | 2025-12-31 | N/A | 7.5 HIGH |
| FastAPI Guard is a security library for FastAPI that provides middleware to control IPs, log requests, and detect penetration attempts. fastapi-guard's penetration attempts detection uses regex to scan incoming requests. However, some of the regex patterns used in detection are extremely inefficient and can cause polynomial complexity backtracks when handling specially crafted inputs. This vulnerability is fixed in 3.0.1. | |||||
| CVE-2021-32837 | 1 Mechanize Project | 1 Mechanize | 2025-12-22 | N/A | 7.5 HIGH |

| CVE-2024-3651 | 1 Kjd | 1 Internationalized Domain Names In Applications | 2025-11-04 | N/A | 7.5 HIGH |
| A vulnerability was identified in the kjd/idna library, specifically within the `idna.encode()` function, affecting version 3.6. The issue arises from the function's handling of crafted input strings, which can lead to quadratic complexity and consequently, a denial of service condition. This vulnerability is triggered by a crafted input that causes the `idna.encode()` function to process the input with considerable computational load, significantly increasing the processing time in a quadratic manner relative to the input size. | |||||
