Title
Grav before 2.0.4 Improper Session Invalidation JWT Access Tokens
Summary
The Grav API plugin (getgrav/grav-plugin-api) before 2.0.4 contains an improper session invalidation vulnerability where JWT access tokens are issued without a jti (JWT ID) claim and therefore cannot be revoked server-side. Unlike refresh tokens, access tokens remain valid for their full lifetime (default 1 hour) regardless of logout, password change, new token issuance, or account disablement. An attacker who has stolen an access token retains full API access until the token naturally expires.
Severity
5.3 (Medium)
