Overview
getgrav/grav is a Modern, Crazy Fast, Ridiculously Easy and Amazingly Powerful Flat-File CMS.
Affected versions of this package are vulnerable to Insufficiently Protected Credentials via the offsetGet process. An attacker can retrieve sensitive user information, such as hashed passwords and two-factor authentication secrets, by invoking offsetGet on user objects within sandboxed templates. This enables offline password cracking and potential authentication bypass. This is only exploitable if the attacker has page-edit permissions.
