Auth bypass in Deluxethemes Media Manager For Userpro
CVE-2024-12821
The Media Manager for UserPro plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the upm_upload_media() function in all versions up to, and including, 3.12.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.
