**Name of the Vulnerable Software and Affected Versions**

**Description**
The issue allows remote attackers to conduct PHP Object Injection attacks. This is achieved by sending crafted serialized data in a salt cookie within a login request to the `includes/classes/ia.core.users.php` file.
**Recommendations**
For Subrion CMS version 4.0.5, as a temporary workaround, consider restricting access to the `includes/classes/ia.core.users.php` file until a patch is available. Avoid using the salt cookie in the affected login request until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
