Overview
getgrav/grav is a Modern, Crazy Fast, Ridiculously Easy and Amazingly Powerful Flat-File CMS.
Affected versions of this package are vulnerable to Insufficient Session Expiration due to the improper invalidation of JWT access tokens, which are issued without a unique identifier and cannot be revoked server-side. An attacker can maintain unauthorized API access by using a stolen access token until it naturally expires, even after user logout, password change, new token issuance, or account disablement.
