MediumCVSS 5.4/10Last modified Jul 1, 2026

Description

Strapi users-permissions plugin fails to restrict JWT algorithms when plugin::users-permissions.jwt.algorithm is not explicitly configured, allowing acceptance of HS384 and HS512 tokens alongside HS256. Attackers possessing the jwtSecret can mint tokens with non-standard HMAC variants to bypass algorithm restrictions and weaken authentication controls.
