Name of the Vulnerable Software and Affected Versions Gutenverse versions prior to 3.4.7

Description The plugin is subject to Reflected Cross-Site Scripting, a flaw where an application includes untrusted data in a web page without proper validation, allowing scripts to be executed in the victim's browser. The issue occurs because the render content() function in class-search-result-title.php outputs the value of the s parameter via get query var('s') directly into the HTML without using esc html() or other escaping functions. Unauthenticated attackers can inject arbitrary web scripts through a crafted URL, which execute when a user clicks the link, provided the gutenverse/search-result-title block is active on the search results template.

Recommendations Update to a version later than 3.4.6. As a temporary workaround, remove the gutenverse/search-result-title block from the site's search results template to minimize the risk of exploitation.
