| CVE-2024-58340 | 2 Langchain, Langchain-ai | 3 Langchain, Langchain Core, Langchain | 2026-03-05 | 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-2025-62484 | 1 Zoom | 4 Meeting Software Development Kit, Workplace, Workplace App and 1 more | 2026-02-26 | 8.1 High |

| CVE-2025-68142 | 1 Facelessuser | 1 Pymdown Extensions | 2026-02-03 | 5.3 Medium |
| PyMdown Extensions is a set of extensions for the `Python-Markdown` markdown project. Versions prior to 10.16.1 have a ReDOS bug found within the figure caption extension (`pymdownx.blocks.caption`). In systems that take unchecked user content, this could cause long hanges when processing the data if a malicious payload was crafted. This issue is patched in Release 10.16.1. As a workaround, those who process unknown user content without timeouts or other safeguards in place to prevent really large, malicious content being aimed at systems may avoid the use of `pymdownx.blocks.caption` until they're able to upgrade. | ||||
| CVE-2025-25200 | 1 Koajs | 1 Koa | 2026-01-20 | 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-2024-28865 | 1 Django-wiki Project | 1 Django-wiki | 2026-01-13 | 7.5 High |
| django-wiki is a wiki system for Django. Installations of django-wiki prior to version 0.10.1 are vulnerable to maliciously crafted article content that can cause severe use of server CPU through a regular expression loop. Version 0.10.1 fixes this issue. As a workaround, close off access to create and edit articles by anonymous users. | ||||
| CVE-2025-53539 | 1 Fastapi-guard | 1 Fastapi Guard | 2025-12-31 | 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-2024-28864 | 1 Ilicmiljan | 1 Secureprops | 2025-12-30 | 2.6 Low |
| SecureProps is a PHP library designed to simplify the encryption and decryption of property data in objects. A vulnerability in SecureProps version 1.2.0 and 1.2.1 involves a regex failing to detect tags during decryption of encrypted data. This occurs when the encrypted data has been encoded with `NullEncoder` and passed to `TagAwareCipher`, and contains special characters such as `\n`. As a result, the decryption process is skipped since the tags are not detected. This causes the encrypted data to be returned in plain format. The vulnerability affects users who implement `TagAwareCipher` with any base cipher that has `NullEncoder` (not default). The patch for the issue has been released. Users are advised to update to version 1.2.2. As a workaround, one may use the default `Base64Encoder` with the base cipher decorated with `TagAwareCipher` to prevent special characters in the encrypted string from interfering with regex tag detection logic. This workaround is safe but may involve double encoding since `TagAwareCipher` uses `NullEncoder` by default. | ||||
| CVE-2021-32837 | 1 Mechanize Project | 1 Mechanize | 2025-12-22 | 7.5 High |
| mechanize, a library for automatically interacting with HTTP web servers, contains a regular expression that is vulnerable to regular expression denial of service (ReDoS) prior to version 0.4.6. If a web server responds in a malicious way, then mechanize could crash. Version 0.4.6 has a patch for the issue. | ||||
| CVE-2025-43764 | 1 Liferay | 4 Digital Experience Platform, Dxp, Liferay Portal and 1 more | 2025-12-12 | 6.5 Medium |
| Self-ReDoS (Regular expression Denial of Service) exists with Role Name search field of Kaleo Designer portlet JavaScript in Liferay Portal 7.4.0 through 7.4.3.131, and Liferay DXP 2024.Q4.0 through 2024.Q4.1, 2024.Q3.0 through 2024.Q3.13, 2024.Q2.1 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.20 and 7.4 GA through update 92, which allows authenticated users with permissions to update Kaleo Workflows to enter a malicious Regex pattern causing their browser to hang for a very long time. | ||||
