This is due to the verify_login() function in app/Login.php containing a missing return statement in the signature verification failure branch \u2014 when Signature::verify2() reports a mismatch, the function only assigns a WP_Error to a local variable and continues executing, causing unconditional fall-through to the login block where Address::log_in() calls wp_set_auth_cookie() regardless of whether the submitted signature is valid. This makes it possible for unauthenticated attackers to log in as any WordPress user who has a linked wallet address \u2014 including administrators \u2014 by submitting that user's public wallet address alongside an arbitrary well-formed signature, enabling full site takeover."}], "lastModified": "2026-09-24T14:42:02.707", "sourceIdentifier": "security@wordfence.com"}
