GHSA-qc5p-3mg5-9fh8: Avo: Broken Access Control Through Unauthorized Execution of Arbitrary Action Classes Across Resources

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.
