{"id":"CVE-2026-19125","state":"PUBLISHED","title":"EthPress <= 2.3.5 - Unauthenticated Authentication Bypass","description":"The EthPress – Web3 Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 2.3.5. 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.","publishedAt":"2026-09-23T21:27:34.233Z","updatedAt":"2026-09-24T13:30:23.425Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["lynn999 EthPress – Web3 Login"],"affected":[{"vendor":"lynn999","product":"EthPress – Web3 Login","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.3.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/267acbd7-379c-4930-aa85-3071dfcac5a5?source=cve","https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Login.php#L46","https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Login.php#L51","https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Plugin.php#L75","https://plugins.trac.wordpress.org/browser/ethpress/tags/2.3.5/app/Address.php#L419","https://plugins.trac.wordpress.org/changeset/3683106/ethpress/trunk/app/Login.php"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/19xxx/CVE-2026-19125.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-19125","state":"PUBLISHED","datePublished":"2026-09-23T21:27:34.233Z","dateUpdated":"2026-09-24T13:30:23.425Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-08-06T15:46:55.338Z"},"containers":{"cna":{"title":"EthPress <= 2.3.5 - Unauthenticated Authentication Bypass","descriptions":[{"lang":"en","value":"The EthPress – Web3 Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 2.3.5.
