At a glance
CVE-2025-14984 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Gutenverse Form WordPress plugin, affecting versions <= 2.3.2. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 2.4.0; sites on affected versions should update now. Disclosed January 2026, reported by andrea bocchetti.
Vulnerability Overview
The Gutenverse Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG file upload in all versions up to, and including, 2.3.2. This is due to the plugin's framework component adding SVG to the allowed MIME types via the upload_mimes filter without implementing any sanitization of SVG file contents. This makes it possible for authenticated attackers, with Author-level access and above, to upload SVG files containing malicious JavaScript that executes when the file is viewed, leading to arbitrary JavaScript execution in victims' browsers.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Gutenverse Form <= 2.3.2 takes an account at Author level or above. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Gutenverse Form the fix is 2.4.0: builds <= 2.3.2 are affected, anything from 2.4.0 onward is not.
Remediation
Update to version 2.4.0, or a newer patched version
How does WordSec protect against this?
An attacker needs Author access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Gutenverse Form 2.4.0 closes this, and updating the plugin is the step that ends it.
