Various Newfold Plugins Various Versions - Unauthenticated Authentication Bypass via Bearer Token Validation with Empty Secret
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.
