CVE-2026-107658 · Severity: medium · CVSS 5.4 · Published 2026-11-06

BuddyForms is a WordPress plugin that allows creation of dynamic forms for content submission. A flaw in input sanitization enables unauthenticated attackers to inject malicious scripts into pages that execute when users visit affected pages. Successful exploitation requires an active public form and a theme with widget support, allowing attackers to inject a malicious widget that runs arbitrary JavaScript in the browser.

## How to fix

## Technical details

The plugin fails to properly sanitize and escape user input in the 'bf_post_type' and 'buddyforms_form_content' parameters, creating a stored XSS vulnerability. An unauthenticated attacker can harvest a valid nonce from a publicly accessible form, then inject malicious JavaScript that persists in the database and executes whenever a user accesses an affected page. The attack leverages WordPress's customize_changeset mechanism to inject a Custom HTML widget into a widgetized sidebar.
