Zammad 5.2.0 suffers from Incorrect Access Control. Zammad did not correctly perform authorization on certain attachment endpoints. This could be abused by an unauthenticated attacker to gain access to attachments, such as emails or attached files.
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.
