CVE-2023-24375

The WordPress Social Login and Register plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the mo_sharing_app_value function as well as others that are reachable via AJAX action in versions up to, and including, 7.5.12. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to change plugin settings.

Additionally, some AJAX actions were missing nonce checks thus making them vulnerable to Cross-Site Request Forgery. This enables unauthenticated attackers to invoke the corresponding functions, granted they can trick an administrator into performing an action such as clicking on a link.
