What is CVE-2024-13646?

The Single-user-chat plugin for WordPress has a vulnerability that permits authenticated attackers, including those with subscriber-level access, to modify data without proper validation. In particular, the 'single_user_chat_update_login' function allows for changes to option values, which could result in denial of service by creating errors on the site. Attackers could exploit this flaw to disrupt legitimate user access or make unauthorized changes to registration settings, thereby significantly affecting the site's functionality.
