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."}],"title":"EthPress <= 2.3.5 - Unauthenticated Authentication Bypass","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/267acbd7-379c-4930-aa85-3071dfcac5a5?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Login.php#L46"},{"url":"https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Login.php#L51"},{"url":"https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Plugin.php#L75"},{"url":"https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Address.php#L419"},{"url":"https://plugins.trac.wordpress.org/changeset/3683106/ethpress/trunk/app/Login.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-287 Improper Authentication","cweId":"CWE-287","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":8.1,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Thatchapol Booranatanit (AliceZz)"}],"timeline":[{"time":"2026-09-06T05:01:44.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-09-23T09:05:24.000Z","lang":"en","value":"Disclosed"}]}}}
