Kerentanan Insufficient Verification of Data Authenticity pada nearform fast-jwt. Skor CVSS 3.1 9.1 (Critical) menurut github.com.

Deskripsi (NVD)

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 process leading to valid tokens returning claims from different valid tokens and users being mis-identified as other users based on the wrong token. Version 6.2.0 contains a patch.
