CVE-2026-24038
Horilla is a free and open source Human Resource Management System (HRMS). In version 1.4.0, the OTP handling logic has a flawed equality check that can be bypassed. When an OTP expires, the server returns None, and if an attacker omits the otp field from their POST request, the user-supplied OTP is also None, causing the comparison user_otp == otp to pass. This allows an attacker to bypass two-factor authentication entirely without ever providing a valid OTP. If administrative accounts are targeted, it could lead to compromise of sensitive HR data, manipulation of employee records, and further system-wide abuse. This issue has been fixed in version 1.5.0.

"value": "Horilla es un Sistema de Gestión de Recursos Humanos (HRMS) gratuito y de código abierto. En la versión 1.4.0, la lógica de manejo de OTP tiene una verificación de igualdad defectuosa que puede ser evitada. Cuando un OTP expira, el servidor devuelve None, y si un atacante omite el campo otp de su solicitud POST, el OTP proporcionado por el usuario también es None, haciendo que la comparación user_otp == otp se apruebe. Esto permite a un atacante evitar completamente la autenticación de dos factores sin proporcionar nunca un OTP válido. Si se dirigen a cuentas de administración, podría llevar al compromiso de datos sensibles de RRHH, manipulación de registros de empleados y a un abuso adicional en todo el sistema. Este problema ha sido solucionado en la versión 1.5.0."
