automation-controller: automation-controller-container: automation-controller: missing use_role authorization on the project signature validation credential foreign key allows a project administrator to bind and use another organization's credential cross-tenant

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. A project has a signature validation credential foreign key used to validate signed project content. Unlike the project's SCM credential, the authorization logic does not verify that the requesting user has use permission on the referenced credential, and the API field has no validator or type restriction. An authenticated user holding only the organization project administrator role can therefore bind an arbitrary credential belonging to another organization, by its identifier, when creating or updating a project. The controller discloses that credential's name and type in the project's summary information and, during project synchronization, decrypts the bound credential and uses it in the attacker-controlled project's update, allowing a cross-tenant authorization boundary violation and information disclosure.

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may obtain information outside the intended access boundary.
