## Technical details

An Authorization Bypass Through User-Controlled Key (Insecure Direct Object Reference) vulnerability exists in PROLIZ OBS before version v26.0328. The flaw (CWE-639) allows an authenticated attacker to perform parameter injection by modifying keys or identifiers within network requests. Because the application fails to properly validate that the requesting user has permission to access the object associated with the modified key, an attacker can retrieve sensitive information belonging to other entities. This vulnerability is exploitable over the network with low privileges and no user interaction. Users are advised to upgrade to version v26.0328 or later.
