CVE-2026-107658

BuddyForms <= 2.10.5 - Unauthenticated Stored Cross-Site Scripting via 'bf_post_type' Parameter via Post-Type Confusion

Published Nov 6, 2026 CVSS 3.1 · 5.4 Medium EPSS < 1% KEV · Not listed
Description
The BuddyForms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'bf_post_type (and buddyforms_form_content)' parameter in all versions up to, and including, 2.10.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that at least one BuddyForms form with public submissions enabled exists on the site (so that the required nonce can be harvested from the public form page) and that the active theme registers a widgetized sidebar, allowing the injected customize_changeset to place a malicious Custom HTML widget into the site's front end.
