CVE-2026-35040 fast-jwt: Stateful RegExp (/g or /y) causes non-deterministic allowed-claim validation (logical DoS)

fast-jwt provides fast JSON Web Token JWT implementation. Prior to 6.2.1, using certain modifiers on RegExp objects in the allowedAud, allowedIss, allowedSub, allowedJti, or allowedNonce options in verify functions can cause certain unintended behaviours. This is because some modifiers are statef...

Name of the Vulnerable Software and Affected Versions Gotenberg versions 8.29.1 and earlier Description Gotenberg uses the dlclark/regexp2 library to compile user-supplied scope patterns without a timeout. This allows users with access to features utilizing this logic to potentially hang workers...

Gotenberg 安全漏洞

Gotenberg is an open-source, developer-friendly API developed by Gotenberg. It is used to convert various document formats into PDF files. Versions of Gotenberg prior to 8.29.1 contained security vulnerabilities. These vulnerabilities stemmed from the use of dlclark/regexp2 to compile user-provid...

CVE-2026-4923

A flaw was found in path-to-regexp. This vulnerability allows a remote attacker to cause a Denial of Service DoS by sending a specially crafted request. The issue arises when multiple wildcards are used with parameters in a way that creates a vulnerable regular expression, leading to excessive...

path-to-regexp vulnerable to Regular Expression Denial of Service via multiple wildcards

Impact When using multiple wildcards, combined with at least one parameter, a regular expression can be generated that is vulnerable to ReDoS. This backtracking vulnerability requires the second wildcard to be somewhere other than the end of the path. Unsafe examples: /foo-bar-:baz /a-:b-c-:d...
