CVE-2026-35039

CRITICAL

9.1

Descripcion

fast-jwt provides fast JSON Web Token (JWT) implementation. From 0.0.1 to before 6.1.0, 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 process leading to valid tokens returning claims from different valid tokens and users being mis-identified as other users based on the wrong token.
