Technical details
The vulnerability exists in the get_user_profile_structure function, where the [pp-custom-html] shortcode processes attacker-controlled base64 payloads containing profile shortcodes like [profile-email], [profile-username], and [profile-date-registered]. Authenticated subscribers can exploit this via the Member Directory's user rebinding, while unauthenticated attackers can inject payloads through the registration handler's reg_nickname and reg_bio fields, which lack nonce validation. The vulnerability allows extraction of sensitive user data without authorization.
