CVE-2026-104797

The Advanced Form Integration — Connect Forms to 300+ Apps plugin for WordPress is vulnerable to Authentication Bypass via Unverified Password Change in all versions up to, and including, 2.9.0 The adfoin ultimatememberac send data function, which powers the Ultimate Member "Update Profile Field" action, resolves the target WordPress user from an attacker-supplied email address and passes an attacker-controlled field key and value directly to UM()->user()->update profile() in the account context — which explicitly bypasses Ultimate Member's banned-key validation — without performing any submitter identity verification, ownership check, capability check, current-password reauthentication, or restriction on sensitive keys such as user pass. This makes it possible for unauthenticated attackers to change the password of any WordPress user account, including Administrator accounts, by submitting a public Contact Form 7 form with a target email and user pass as the field key, enabling full site takeover. Exploitation requires an administrator to have pre-configured a Contact Form 7 integration that maps the target email, field key, and value from public form inputs to the Ultimate Member Update Profile Field action — the exact workflow the plugin's own UI advertises for this action type.
