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.
Affected products
- Themekraft BuddyForms up to and including 2.10.5
