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."}],"title":"Various Newfold Plugins Various Versions - Unauthenticated Authentication Bypass via Bearer Token Validation with Empty Secret","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/3ee369c0-0d7c-4142-b3ba-a518288647ba?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L222"},{"url":"https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L201"},{"url":"https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L191"},{"url":"https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/HiiveConnection.php#L406"},{"url":"https://plugins.trac.wordpress.org/browser/wp-module-data/trunk/includes/Data.php#L69"},{"url":"https://github.com/newfold-labs/wp-module-data/commit/9d913fd8fa12796c4d9c09081e4aeccfa5cb1301"},{"url":"https://github.com/newfold-labs/wp-plugin-hostgator/compare/3.2.0...3.2.1"},{"url":"https://github.com/newfold-labs/wp-plugin-bluehost/compare/4.19.0...4.19.1"},{"url":"https://github.com/newfold-labs/wp-plugin-web/compare/2.3.5...2.3.6"},{"url":"https://github.com/newfold-labs/wp-plugin-crazy-domains/compare/2.5.2...2.5.3"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-287 Improper Authentication","cweId":"CWE-287","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"sorin vasile"}],"timeline":[{"time":"2026-09-08T20:12:14.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-09T15:41:26.162294Z","id":"CVE-2026-80099","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-09T16:02:13.368Z"}}]}}
