CVE-2026-100106

The FiboSearch – Ajax Search for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'purchased plan' parameter in all versions up to, and including, 1.34.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that the site owner has previously completed the standard Freemius opt-in flow; once that condition is met, any Subscriber can reach the vulnerable handler simply by loading /wp-admin/profile.php with the requisite query parameters.
