CVE-2021-24752Public exploitNetwork attack vector

Subscriber configuration changes via unchecked AJAX action

Published Oct 18, 2021 · Updated Aug 3, 2024

Improper access control in 17 Catch Themes WordPress plugins before their listed fixes allows remote authenticated users to change settings. The ctp_switch AJAX action accepts attacker-supplied option_name and value fields without capability or CSRF checks, then changes plugin configuration. Subscriber-level access is sufficient; exploitation through CSRF additionally requires a logged-in user to trigger a crafted request.
