What is CVE-2026-15941?
CVE-2026-15941 is a medium-severity SQL injection vulnerability in Relevanssi Premium – A Better Search, published on 5 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The plugin provides an Admin Search page that allows users with the `edit_posts` capability to run Relevanssi searches from the WordPress dashboard. The AJAX handler accepts a URL-encoded `args` parameter, parses it into a `WP_Query`, and then passes user-controlled taxonomy query data into Relevanssi's taxonomy restriction builder. The taxonomy value is sanitized as text but is not parameterized for SQL before being interpolated into a term taxonomy lookup query. This allows an authenticated contributor-level attacker to inject SQL through the Admin Search AJAX request and execute time-based blind SQL injection against the WordPress database.
