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...

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-2026-34950

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...
