What the vulnerability does
01Description
The FiboSearch – Ajax Search for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `thegem_te_search` shortcode in all versions up to, and including, 1.32.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability requires TheGem theme (premium) to be installed with Header Builder mode enabled, and the FiboSearch "Replace search bars" option enabled for TheGem integration.
