CVE-2026-3001
Received Received - Intake
Reflected XSS in Gutenverse WordPress Plugin

Publication date: 2026-05-27

Last updated on: 2026-05-27

Assigner: Wordfence

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.

Can you explain this vulnerability to me?

The Gutenverse plugin for WordPress has a Reflected Cross-Site Scripting (XSS) vulnerability in all versions up to and including 3.4.6. This occurs because the plugin does not properly sanitize or escape the input received via the 's' parameter in search queries.

Specifically, the vulnerability exists in the `render_content()` method of the `class-search-result-title.php` file, where the value from `get_query_var('s')` is output directly into the page HTML without using escaping functions like `esc_html()`. This allows an attacker to craft a malicious URL that injects arbitrary web scripts, which execute if a user clicks the link and the `gutenverse/search-result-title` block is present on the search results page.


How can this vulnerability impact me? :

This vulnerability can allow unauthenticated attackers to inject and execute arbitrary scripts in the context of the affected website when a user clicks a crafted URL. This can lead to theft of user credentials, session hijacking, defacement, or redirection to malicious sites.

Because the attack is reflected, it requires user interaction (clicking the malicious link), but the impact can still be significant, especially if users are tricked into clicking such links.
