Description
The YITH WooCommerce Product Add-Ons plugin for WordPress is vulnerable to SQL Injection via the 's' parameter of the add-on blocks list in versions 4.29.1 up to, and including, 4.34.0, due to an incomplete fix for CVE-2026-42383. The user-supplied search term is placed inside a LIKE clause without escaping or a prepared statement in the default, unfiltered blocks list. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to append additional SQL queries to existing queries that can be used to extract sensitive information from the database.
