Vulnerability from github – Published: 2026-08-05 06:30 – Updated: 2026-08-05 06:30

Details

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.

Severity

6.5 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
