Open WebUI: ReDoS in skill-mention regexes causes whole-instance DoS on default config

Summary Two regexes in backend/openwebui/utils/middleware.py that parse skill-mention tags backtrack in On² on input that contains . Both run synchronously, on the asyncio event loop, on every chat completion with no feature gate. Because the default deployment is a single uvicorn worker, one suc...

A flaw was found in libssh. A remote attacker, by controlling client configuration files or knownhosts files, could craft specific hostnames that when processed by the matchpattern function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion,...

Regular Expression Denial Of Service

angular-sanitize is vulnerable to Regular Expression Denial Of Service ReDoS. The vulnerability is due to a regular expression in the linky filter that exhibits super-linear backtracking, allowing attackers to supply crafted input that causes excessive CPU consumption and results in a denial of...

Summary Multiple vulnerabilities were addressed in IBM Event Streams version 13.0.0 Vulnerability Details CVEID:CVE-2026-4867 DESCRIPTION: Impact: A bad regular expression is generated any time you have three or more parameters within a single segment, separated by something that is not a period...

Gitea: Unauthenticated ReDoS via CODEOWNERS pattern matching allows denial of service

This issue has been found by a security agent and review by myself. Gitea's CODEOWNERS feature uses the regexp2 library to match file paths against ownership rules. User-supplied patterns are passed directly to regexp2.Compile with no sanitisation and no match timeout. This allows an attacker to...
