{"id":"CVE-2026-85682","state":"PUBLISHED","title":"YOP Poll <= 7.0.10 - Unauthenticated Origin Validation Error to Administrator Account Takeover via '/auth/wp-login-redirect' REST Route","description":"The YOP Poll plugin for WordPress is vulnerable to Origin Validation Error in all versions up to, and including, 7.0.10. This is due to the plugin transmitting a wp_rest nonce to window.opener via postMessage() with a wildcard targetOrigin. This makes it possible for unauthenticated attackers to steal a REST nonce scoped to a logged-in Administrator and use it to change the Administrator's email address and password, resulting in full account takeover. The Administrator must open an attacker-controlled page in order to exploit this vulnerability.","publishedAt":"2026-09-24T08:27:32.067Z","updatedAt":"2026-09-24T14:35:13.603Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["yourownprogrammer YOP Poll"],"affected":[{"vendor":"yourownprogrammer","product":"YOP Poll","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"7.0.10","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/b3574182-1bda-49b2-aac7-60f862891b46?source=cve","https://plugins.trac.wordpress.org/changeset/3690945/"],"weaknesses":["CWE-346"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/85xxx/CVE-2026-85682.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-85682","state":"PUBLISHED","datePublished":"2026-09-24T08:27:32.067Z","dateUpdated":"2026-09-24T14:35:13.603Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-04T13:42:23.410Z"},"containers":{"cna":{"title":"YOP Poll <= 7.0.10 - Unauthenticated Origin Validation Error to Administrator Account Takeover via '/auth/wp-login-redirect' REST Route","descriptions":[{"lang":"en","value":"The YOP Poll plugin for WordPress is vulnerable to Origin Validation Error in all versions up to, and including, 7.0.10.
