Detailsinfo

A vulnerability was found in themekraft BuddyForms Plugin up to 2.10.5. It has been rated as critical. This issue affects the function buddyforms_form_response_no_ajax/buddyforms_edit_form_save_meta_box_data of the component Frontend Submission Handler. The manipulation of the argument bf_post_type/buddyforms_options with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The BuddyForms plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.10.5 via a form-type confusion attack through the `bf_post_type` parameter. This is due to the public frontend submission handler `buddyforms_form_response_no_ajax()` authorizing logged-out submissions based solely on the target form's `public_submit` flag while independently trusting the attacker-supplied `$_POST['bf_post_type']` to determine the post type of the newly created object — a cross-check introduced in 2.10.2 applies only to existing posts (`post_id != 0`) and is completely bypassed for new-object creation — combined with the `save_post` listener `buddyforms_edit_form_save_meta_box_data()` lacking both a `current_user_can()` capability check and a form-builder nonce, causing it to unconditionally persist attacker-supplied `$_POST['buddyforms_options']` for any newly inserted `buddyforms` CPT post. This makes it possible for unauthenticated attackers to insert a rogue BuddyForms form configuration with an attacker-controlled `new_user_role` value into the live global form registry, then submit a registration through that form to create a new WordPress account with administrator-level privileges and achieve full site takeover. Exploitation requires the WordPress site to have "Anyone can register" enabled and at least one public BuddyForms form attached to a page, both of which are standard BuddyForms deployment configurations.

It is possible to read the advisory at wordfence.com. The identification of this vulnerability is CVE-2026-107622 since 10/08/2026. The exploitation is known to be easy.
