The flaw exists within the Register \u0026amp; Login add-on, specifically inside the before_email_success_msg() function. This function improperly handles client-submitted data by whitelisting the 'role' key and passing it directly into the user-data array processed by wp_insert_user().\u003c/p\u003e\n\u003cp\u003eBecause the input is not validated against administrative settings, lacks an allow-list, and performs no capability checks via current_user_can(), unauthenticated attackers can inject the parameter 'role=administrator' into any public Super Forms registration form. This allows the creation of unauthorized accounts with full administrative privileges, granting the attacker complete control over the compromised WordPress instance. Defenders should identify all WordPress installations using Super Forms and ensure they are upgraded to a version beyond 6.3.316 or disable the Register \u0026amp; Login add-on immediately.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies a target WordPress site utilizing the Super Forms - Drag \u0026amp; Drop Form Builder plugin.\u003c/li\u003e\n\u003cli\u003eAttacker locates a public-facing registration form created with the Super Forms plugin.\u003c/li\u003e\n\u003cli\u003eAttacker initiates an HTTP POST request to the form handler, specifying register_login_action='register'.\u003c/li\u003e\n\u003cli\u003eAttacker injects the 'role=administrator' parameter into the registration form submission data.\u003c/li\u003e\n\u003cli\u003eThe server-side before_email_success_msg() function in the Register \u0026amp; Login add-on accepts the malicious 'role' key without validation.\u003c/li\u003e\n\u003cli\u003eThe system executes wp_insert_user() using the attacker-supplied role data.\u003c/li\u003e\n\u003cli\u003eA new user account is created with Administrator privileges.\u003c/li\u003e\n\u003cli\u003eAttacker authenticates with the newly created account to establish persistent administrative access.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation allows unauthenticated attackers to gain full administrative access to affected WordPress installations.
