CVE-2026-35039

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 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...
