CVE-2026-3001 Details
Description
The Gutenverse plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in all versions up to, and including, 3.4.6 due to insufficient input sanitization and output escaping. Specifically, the `render_content()` method in `class-search-result-title.php` outputs the value of `get_query_var('s')` directly into the page HTML without applying `esc_html()` or any other escaping function. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages via a crafted URL that execute if a user clicks the link, provided the `gutenverse/search-result-title` block is present on the site's search results template.
A reflected cross-site scripting vulnerability has been identified in the Gutenverse plugin for WordPress, affecting all versions through 3.4.6. The issue arises from inadequate input sanitization and output escaping. Specifically, the vulnerability is located in the 'render_content()' method of 'class-search-result-title.php', where the 's' parameter is output directly into the HTML without proper escaping. This flaw allows unauthenticated attackers to inject arbitrary scripts into pages via a crafted URL, which would execute when a user clicks the link, provided the 'gutenverse/search-result-title' block is active on the site's search results template.
Users can update to Gutenverse version 3.4.7 or a newer patched version to address this vulnerability.
