Description
The YMC Filter plugin for WordPress is vulnerable to Sensitive Information Exposure via the keyword search of the posts/filter REST endpoint in all versions up to, and including, 3.12.20, due to the meta-field search condition being appended to the end of the query's WHERE clause as an unparenthesised 'OR pm.meta_value LIKE' condition, which overrides the post status and other query restrictions. This makes it possible for unauthenticated attackers to retrieve draft, private, and other non-published posts and revisions whose meta values match a search term, on grids where meta-field search is enabled.
