PT-2026-31622

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...

PT-2026-31621

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...

fast-jwt 安全漏洞

fast-jwt is a JSON Web Token implementation open-sourced by Nearform. Versions of fast-jwt up to 6.2.0 contained security vulnerabilities. These vulnerabilities occurred when the allowedAud verification option used regular expressions, and if the aud declaration controlled by the attacker trigger...

CVE-2026-39376

FastFeedParser is affected by CVE-2026-39376 prior to version 0.5.10. When parse() fetches a URL returning an HTML page with a tag, it may recursively call itself on the redirect URL without a depth limit, visited-URL deduplication, or redirect count cap. An attacker-controlled server that emits...

CVE-2026-39376 FastFeedParser has an infinite redirect loop DoS via meta-refresh chain

FastFeedParser is a high performance RSS, Atom and RDF parser. Prior to 0.5.10, when parse fetches a URL that returns an HTML page containing a tag, it recursively calls itself with the redirect URL — with no depth limit, no visited-URL deduplication, and no redirect count cap. An...

CVE-2026-34950

fast-jwt provides fast JSON Web Token JWT implementation. In 6.1.0 and earlier, the publicKeyPemMatcher regex in fast-jwt/src/crypto.js uses a ^ anchor that is defeated by any leading whitespace in the key string, re-enabling the exact same JWT algorithm confusion attack that CVE-2023-48223 patch...

CVE-2026-35039

fast-jwt provides fast JSON Web Token JWT implementation. From 0.0.1 to before 6.2.0, setting up a custom cacheKeyBuilder method which does not properly create unique keys for different tokens can lead to cache collisions. This could cause tokens to be mis-identified during the verification proce...

XML Entity Expansion

fast-xml-parser is vulnerable to XML Entity Expansion. The vulnerability is due to missing enforcement of entity expansion limits for numeric and standard XML entities, which allows an attacker to supply crafted XML with excessive entity references to trigger high memory and CPU consumption leadi...

freerdp: FreeRDP: Denial of Service via FastGlyph parsing buffer overflow

A flaw was found in FreeRDP. A malicious server can exploit a vulnerability in FastGlyph parsing, which improperly trusts data length without sufficient validation. This can lead to a client-side global buffer overflow, resulting in a denial of service DoS due to a crash. For this vulnerability t...

CVE-2026-35042 fast-jwt accepts unknown `crit` header extensions (RFC 7515 §4.1.11 MUST violation)

fast-jwt provides fast JSON Web Token JWT implementation. In 6.1.0 and earlier, fast-jwt does not validate the crit Critical Header Parameter defined in RFC 7515 §4.1.11. When a JWS token contains a crit array listing extensions that fast-jwt does not understand, the library accepts the token...

CVE-2026-35042

The CVE concerns fast-jwt (up to and including 6.1.0) not validating the RFC 7515 §4.1.11 crit header parameter, causing tokens with an unknown crit extension to be accepted instead of rejected. Affected components are the fast-jwt library (Node.js) and related advisories (GHSA-hm7r-c7qw-ghp6) wi...
