Summary
The FiboSearch Ajax Search for WooCommerce plugin by damian-gora is affected in all versions up to and including 1.34.2. The 'purchased_plan' parameter is not sanitized or escaped, which lets attacker-supplied scripts be stored (CWE-79). An authenticated attacker with Subscriber access or higher can inject scripts that run in the browser of any user who opens an injected page, once the site owner has completed the Freemius opt-in flow.

Description from the CNA
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.
