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.

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required.
