A fix is available in Grav CMS version 2.0.16 and later. Users should upgrade to version 2.0.16 or newer to remediate this vulnerability. No additional mitigation steps are indicated in the advisory.
Description
Grav CMS versions before 2.0.16 contain a vulnerability in sandboxed Twig templates where allow-listed offsetGet() and offsetexists() methods on User objects do not filter sensitive fields. This allows attackers with page-edit permissions to access hashed passwords and two-factor authentication secrets. The vulnerability enables offline password cracking and potential authentication bypass.
