The record
A critical Broken Access Control vulnerability was identified in the `ActionsController` of the Avo framework (v3.x). Due to insecure action lookup logic, an authenticated user can execute any Action class (descendants of `Avo::BaseAction`) on any resource, even if the action is not registered for that specific resource. This leads to Privilege Escalation and unauthorized data manipulation across the entire application.
