{"id":"CVE-2026-9178","state":"PUBLISHED","title":"WP Forms Connector <= 1.8 - Missing Authorization to Unauthenticated Information Exposure via 'user/list' REST Endpoint","description":"The WP Forms Connector plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 1.8. The plugin registers the REST route wp/v3/user/list/<id> (callback userDetail()) with permission_callback set to '__return_true', and the function's home-grown authentication only verifies that the supplied 'Username' HTTP header maps to an administrator account and that a 'Password' HTTP header is non-empty. It never validates the password with wp_check_password() (unlike the sibling delete_wc_user() function which does). This makes it possible for unauthenticated attackers to retrieve sensitive information for any registered user ID — including the WordPress password hash (user_pass) and email address — by sending a request with a valid administrator login name (commonly the default 'admin') and any arbitrary password value.","publishedAt":"2026-06-24T05:33:33.451Z","updatedAt":"2026-06-24T12:13:00.298Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["hancock11 WP Forms Connector"],"affected":[{"vendor":"hancock11","product":"WP Forms Connector","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/f5dfafee-9b6c-4e57-b263-39ff15cd3b51?source=cve","https://plugins.trac.wordpress.org/browser/wp-forms-connector/tags/1.8/WP-Forms-Connector.php#L1490","https://plugins.trac.wordpress.org/browser/wp-forms-connector/tags/1.8/WP-Forms-Connector.php#L1477","https://plugins.trac.wordpress.org/browser/wp-forms-connector/tags/1.8/WP-Forms-Connector.php#L1464","https://plugins.trac.wordpress.org/browser/wp-forms-connector/tags/1.8/WP-Forms-Connector.php#L739"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:13:52.441Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/9xxx/CVE-2026-9178.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-9178","state":"PUBLISHED","datePublished":"2026-06-24T05:33:33.451Z","dateUpdated":"2026-06-24T12:13:00.298Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-21T14:44:27.753Z"},"containers":{"cna":{"title":"WP Forms Connector <= 1.8 - Missing Authorization to Unauthenticated Information Exposure via 'user/list' REST Endpoint","descriptions":[{"lang":"en","value":"The WP Forms Connector plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 1.8.
