AI-suggested
If you cannot patch yet, consider restricting access to the affected REST API endpoint or disabling the YMC Filter plugin if feasible.
Description
The YMC Filter WordPress plugin before 3.11.3 does not properly authorize access to one of its REST API endpoints and does not validate a user-supplied query parameter, allowing unauthenticated attackers to retrieve the titles and content of private, draft, and other non-public posts.
