{"id":"CVE-2026-80099","state":"PUBLISHED","title":"Various Newfold Plugins Various Versions - Unauthenticated Authentication Bypass via Bearer Token Validation with Empty Secret","description":"Several Newfold plugins are vulnerable to Authentication Bypass. The vulnerability exists because the plugins bundle the wp-module-data module. In the module, the `authenticate()` method — registered on the `rest_authentication_errors` filter and therefore evaluated for every unauthenticated REST API request — performs an HMAC-style Bearer token comparison that degenerates when `HiiveConnection::get_auth_token()` returns `false`: PHP coerces `strrev(false)` to `strrev('')`, collapsing the secret salt to the publicly known constant `hash('sha256', '') = e3b0c44...`, while all remaining hash inputs (HTTP method, request URL, raw request body, and the `X-Timestamp` header) remain fully attacker-controlled. This makes it possible for unauthenticated attackers to compute a valid Bearer token entirely offline, pass the token equality check, and have `wp_set_current_user()` invoked against the first administrator returned by `get_users(['role' => 'administrator'])`, granting full administrator-level access and enabling arbitrary REST API operations such as creating new administrator accounts and achieving complete site takeover. Vulnerable versions are WP Plugin Crazy Domains (<= 2.5.2), WP Plugin Web (<= 2.3.4), WP Plugin Hostgator (<= 3.1.0), WP Plugin Bluehost (<= 4.17.1). The affected module is vulnerable in versions up to, and including, 2.9.4.","publishedAt":"2026-09-09T08:28:22.335Z","updatedAt":"2026-09-09T16:02:13.368Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["Newfold WP Plugin Web","Newfold WP Plugin Crazy Domains","Newfold WP Module Data","Newfold WP Plugin Hostgator","Newfold WP Plugin Bluehost"],"affected":[{"vendor":"Newfold","product":"WP Plugin Web","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.3.5","versionType":"semver"}]},{"vendor":"Newfold","product":"WP Plugin Crazy Domains","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.5.2","versionType":"semver"}]},{"vendor":"Newfold","product":"WP Module Data","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.9.7","versionType":"semver"}]},{"vendor":"Newfold","product":"WP Plugin Hostgator","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.2.0","versionType":"semver"}]},{"vendor":"Newfold","product":"WP Plugin Bluehost","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.19.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3ee369c0-0d7c-4142-b3ba-a518288647ba?source=cve","https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L222","https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L201","https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L191","https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/HiiveConnection.php#L406","https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L69","https://github.com/newfold-labs/wp-module-data/commit/9d913fd8fa12796c4d9c09081e4aeccfa5cb1301","https://github.com/newfold-labs/wp-plugin-hostgator/compare/3.2.0...3.2.1","https://github.com/newfold-labs/wp-plugin-bluehost/compare/4.19.0...4.19.1","https://github.com/newfold-labs/wp-plugin-web/compare/2.3.5...2.3.6","https://github.com/newfold-labs/wp-plugin-crazy-domains/compare/2.5.2...2.5.3"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/80xxx/CVE-2026-80099.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-80099","state":"PUBLISHED","datePublished":"2026-09-09T08:28:22.335Z","dateUpdated":"2026-09-09T16:02:13.368Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-08-25T18:44:30.101Z"},"containers":{"cna":{"title":"Various Newfold Plugins Various Versions - Unauthenticated Authentication Bypass via Bearer Token Validation with Empty Secret","descriptions":[{"lang":"en","value":"Several Newfold plugins are vulnerable to Authentication Bypass.
