No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Plugin Organizer plugin for WordPress is vulnerable to SQL Injection via the 'PO_plugin_path' parameter in versions up to, and including, 10.2.4. This is due to insufficient escaping on the user-supplied parameter in the perform_plugin_search() function, where esc_sql() output is passed as the replacement string to preg_replace(), which collapses backslash escapes and defeats the quoting protection; additionally, the AJAX handler lacks both nonce verification and capability checks. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
