Plugin Organizer plugin search permits subscriber-level SQL injection
Plugin Organizer through 10.2.4 registers the authenticated AJAX action PO_perform_plugin_search without restricting it beyond a logged-in WordPress account. The perform_plugin_search() handler lacks nonce and capability checks and reads the attacker-controlled PO_plugin_path POST parameter. It places esc_sql() output into preg_replace() replacement strings used to construct several queries; replacement processing collapses backslash escapes before the resulting SQL reaches $wpdb->get_var() and $wpdb->get_results(). A Subscriber can therefore inject into the existing queries and extract sensitive database information. Version 10.2.5 requires the activate_plugins capability and a valid plugin nonce and replaces preg_replace() with str_replace().

This CVE was published Jul 28, 2026 and is one of 2 known issues for this plugin.
Update, patch or deactivate.
Update Plugin Organizer to 10.2.5 or later. Review authenticated requests to admin-ajax.php with action=PO_perform_plugin_search, particularly those from low-privilege accounts.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
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.
