The endpoints are dispatched from SwpmInitTimeTasks::check_and_do_email_activation() on frontend init with no authentication, nonce, capability, or ownership check, and the recipient address used by SwpmRegistration::send_reg_email() is taken from an attacker-controlled $_POST['email'] parameter (overriding the member's registered address). This makes it possible for unauthenticated attackers to redirect an arbitrary pending member's activation email \u2014 and the follow-up 'registration complete' email containing the member's username and plaintext password \u2014 to an attacker-chosen address, and to then activate that member's account without their consent."}], "lastModified": "2026-10-06T15:04:52.637", "sourceIdentifier": "security@wordfence.com"}
