Mattermost versions 9.11.x <= 9.11.8 fail to enforce proper access controls on the /api/v4/audits endpoint, allowing users with delegated granular administration roles who lack access to Compliance Monitoring to retrieve User Activity Logs.

The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
