CVE-2026-35041 ReDoS in fast-jwt when using RegExp in allowed* leading to CPU exhaustion during token verification

fast-jwt provides fast JSON Web Token JWT implementation. From 5.0.0 to 6.2.0, a denial-of-service condition exists in fast-jwt when the allowedAud verification option is configured using a regular expression. Because the aud claim is attacker-controlled and the library evaluates it against the...

CVE-2026-35040

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...

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...

minimatch: minimatch: Denial of Service via specially crafted glob patterns

A flaw was found in minimatch. A remote attacker could exploit this Regular Expression Denial of Service ReDoS vulnerability by providing a specially crafted glob pattern. This pattern, containing numerous consecutive wildcard characters, causes excessive processing and exponential backtracking i...

ruby: Arbitrary memory address read vulnerability with Regex search

A flaw was found in Ruby. If attacker-supplied data is provided to the Ruby regex compiler, it is possible to extract arbitrary heap data relative to the start of the text, including pointers and sensitive strings...

fast-jwt 安全漏洞

fast-jwt is a JSON Web Token implementation open-sourced by Nearform. Versions of fast-jwt prior to 6.2.1 contained a security vulnerability. This vulnerability stemmed from the use of regular expression objects with state modifiers in certain options of the verify function, which could cause 50%...

unhead 安全漏洞

Unhead is a document header and template manager open source by UnJS. Versions of Unhead prior to 2.1.13 contained security vulnerabilities; these vulnerabilities stemmed from regular expression restrictions during the decoding of HTML entities, which could lead to cross-site scripting attacks...
