CVE-2026-35042
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-2026-35039 — fast-jwt cacheKeyBuilder collision leads to identity/authorization mixups Multiple connected sources describe a cache-confusion vulnerability in fast-jwt where a user-supplied cacheKeyBuilder can fail to produce unique keys for different tokens. When caching is enabled, two disti...
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...
CVE-2026-35039 fast-jwt Affected by Cache Confusion via cacheKeyBuilder Collisions Can Return Claims From a Different Token (Identity/Authorization Mixup)
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...
CVE-2026-35030 LiteLLM has an authentication bypass via OIDC userinfo cache key collision
LiteLLM is a proxy server AI Gateway to call LLM APIs in OpenAI or native format. Prior to 1.83.0, when JWT authentication is enabled enablejwtauth: true, the OIDC userinfo cache uses token:20 as the cache key. JWT headers produced by the same signing algorithm generate identical first 20...
CVE-2026-35030
LiteLLM (proxy for LLM APIs) contains an authentication bypass flaw when JWT/OIDC authentication is enabled. The OIDC userinfo cache key is derived from the first 20 characters of the token, allowing an unauthenticated attacker to craft a token whose prefix matches a legitimate user’s cached toke...

Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption JWE, JSON Web Signature JWS, and JSON Web Token JWT standards. Prior to 4.1.4 and 3.0.5, decrypting a JSON Web Encryption JWE object will panic if t...
CVE-2026-34950
CVE-2026-34950 affects the fast-jwt library (6.1.0 and earlier). The publicKeyPemMatcher in fast-jwt/src/crypto.js uses an anchored regex starting with ^, which is defeated by any leading whitespace in the key string. This misclassifies RSA public keys with leading whitespace, allowing an attacke...
CVE-2026-34950 fast-jwt has an incomplete fix for CVE-2023-48223: JWT Algorithm Confusion via Whitespace-Prefixed RSA Public Key
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-2026-37977
A flaw was found in Keycloak. A remote attacker can exploit a Cross-Origin Resource Sharing CORS header injection vulnerability in Keycloak's User-Managed Access UMA token endpoint. This flaw occurs because the azp claim from a client-supplied JSON Web Token JWT is used to set the...

fast-jwt 安全漏洞
fast-jwt is a JSON Web Token implementation open-sourced by Nearform. Versions of fast-jwt up to 6.1.0 contained security vulnerabilities, which stemmed from the lack of verification of the crit header parameter. This allowed tokens containing unknown extensions to be accepted...
LiteLLM 授权问题漏洞
LiteLLM is an open-source application developed by Berri AI. It allows for the invocation of all LLM APIs in the OpenAI format. Prior to version 1.83.0, LiteLLM had an authorization vulnerability. This vulnerability stemmed from the use of token:20 as a cache key when JWT authentication was...
