{"id":"CVE-2026-80099","summary":"Various Newfold Plugins Various Versions - Unauthenticated Authentication Bypass via Bearer Token Validation with Empty Secret","details":"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' =\u003e '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 (\u003c= 2.5.2), WP Plugin Web (\u003c= 2.3.4), WP Plugin Hostgator (\u003c= 3.1.0), WP Plugin Bluehost (\u003c= 4.17.1). The affected module is vulnerable in versions up to, and including, 2.9.4.","modified":"2026-09-10T03:49:57.601214306Z","published":"2026-09-09T08:28:22.335Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80099.json","cna_assigner":"Wordfence","cwe_ids":["CWE-287"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80099.json"},{"type":"FIX","url":"https://github.com/newfold-labs/wp-module-data/commit/9d913fd8fa12796c4d9c09081e4aeccfa5cb1301"},{"type":"WEB","url":"https://github.com/newfold-labs/wp-plugin-bluehost/compare/4.19.0...4.19.1"},{"type":"WEB","url":"https://github.com/newfold-labs/wp-plugin-crazy-domains/compare/2.5.2...2.5.3"},{"type":"WEB","url":"https://github.com/newfold-labs/wp-plugin-hostgator/compare/3.2.0...3.2.1"},{"type":"WEB","url":"https://github.com/newfold-labs/wp-plugin-web/compare/2.3.5...2.3.6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80099"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L191"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L201"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L222"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L69"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/HiiveConnection.php#L406"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/3ee369c0-0d7c-4142-b3ba-a518288647ba?source=cve"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/newfold-labs/wp-module-data","events":[{"introduced":"0"},{"last_affected":"bd9642c155735fac8f114ea1eb237da4a72eb267"},{"last_affected":"9abdcb0e9153a6e231c3ff299d9f21a784e0f86c"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"2.5.2"},{"last_affected":"2.9.7"}],"source":"AFFECTED_FIELD"}}],"versions":["2.9.7","2.9.6","2.9.5","2.9.4","2.9.3","2.9.2","2.9.1","2.9.0","2.8.8","2.8.7","2.8.6","2.8.5","2.8.4","2.8.3","2.8.2","2.8.1","2.8.0","2.7.2","2.7.1","2.7.0","2.6.13","2.6.12","2.6.11","2.6.10","2.6.9","2.6.8","2.6.7","2.6.6","2.6.5","2.6.4","2.6.3","2.6.2","2.6.1","2.6.0","2.5.3","2.5.2","2.5.1","2.5.0","2.4.24","2.4.23","2.4.22","2.4.21","2.4.20","2.4.19","2.4.18","2.4.17","2.4.16","2.4.15","2.4.14","2.4.13","2.4.12","2.4.11","2.4.10","2.4.9","2.4.8","2.4.7","2.4.6","2.4.5","2.4.4","2.4.3","2.4.2","2.4.1","2.4.0","2.3.4","2.3.3","2.3.2","2.3.1","2.3","2.2.5","2.2.4","2.2.3","2.2.2","2.2.1","2.2","2.1","2.0.1","2.0.0","2.0.0.beta1","1.8.3","1.8.2","1.8.1","1.8","1.7","1.6.1","1.6","1.5","1.4.3","1.4.1","1.4.2","1.4","1.3","1.2.1","1.2","1.1","1.0.2","1.0.1","1.0","0.1.2","0.1.1","0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80099.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/newfold-labs/wp-plugin-bluehost","events":[{"introduced":"0"},{"last_affected":"fa91db4bdd3734c98a57fd6c35090e0b54e9ee4a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"4.19.0"}],"source":"AFFECTED_FIELD"}}],"versions":["4.19.0","4.18.2","4.18.1","4.18.0","4.17.3","4.17.2","4.17.1","4.17.0","4.16.1","4.16.0","4.15.1","4.15.0","4.13.1","4.14.2","4.14.1","4.14.0","4.13.2","4.13.0","4.12.1","4.12.0","4.11.0","4.10.0","4.9.0","4.8.0","4.7.2","4.7.1","4.7.0","4.6.3","4.6.2","4.6.1","4.6.0","4.5.1","4.5.0","4.4.2","4.4.1","4.4.0","4.3.10","4.3.9","4.3.8","4.3.7","4.3.6","4.3.5","4.3.4","4.3.3","4.3.2","4.3.1","4.2.1","4.3.0","4.2.0","4.1.5","4.1.4","4.1.3","4.1.2","4.1.1","4.1.0","4.0.7","4.0.6","4.0.5","4.0.4","4.0.3","4.0.2","4.0.1","4.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80099.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/newfold-labs/wp-plugin-hostgator","events":[{"introduced":"0"},{"last_affected":"e1adef3231b465a84203796c02c872fa744b49ad"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"3.2.0"}],"source":"AFFECTED_FIELD"}}],"versions":["3.2.0","3.1.0","3.0.2","3.0.1","3.0.0","2.15.2","2.15.1","2.15.0","2.14.1","2.14.0","2.13.3","2.13.2","2.13.1","2.13.0","2.12.6","2.12.5","2.12.4","2.12.3","2.12.2","2.12.1","2.12.0","2.11.8","2.11.7","2.11.6","2.11.5","2.11.4","2.11.3","2.11.2","2.11.1","2.11.0","2.10.3","2.10.2","2.10.1","2.10.0","2.9.3","2.9.2","2.9.1","2.9.0","2.8.0","2.7.2","2.7.1","2.7.0","2.6.3","2.6.2","2.6.1","2.6.0","2.5.1","2.5.0","2.4.1","2.4.0","2.3.2","2.3.1","2.3.0","2.2.0","2.1.0","2.0.0","1.2.10","1.2.9","1.2.0","1.1.1","1.0.3","1.0.2","1.0.1","1.0.0","0.9.12","0.9.11","0.9.10","0.9.9","0.9.8","0.9.7","0.9.6","0.9.4","0.9.3","0.9.2","0.9.1","0.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80099.json"}},{"rang
