This is due to the verify_login() function in app/Login.php containing a missing return statement in the signature verification failure branch — 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 — including administrators — by submitting that user's public wallet address alongside an arbitrary well-formed signature, enabling full site takeover.","published":"2026-09-23T22:16:56.683","modified":"2026-09-24T14:42:02.707","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Address.php#L419"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Login.php#L46"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Login.php#L51"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Plugin.php#L75"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3683106/ethpress/trunk/app/Login.php"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/267acbd7-379c-4930-aa85-3071dfcac5a5?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-24T14:42:02.707"}}
