CVE-2025-10503

The authentication endpoint accepts user-supplied input without enforcing expected validation constraints, leading to a lack of proper output encoding. This allows for the injection of malicious JavaScript payloads, enabling reflected cross-site scripting. An attacker can leverage this vulnerability to redirect the user's browser to a malicious website, modify the user interface of the web page, retrieve information from the browser, or cause other harmful actions. However, due to the protection of session-related cookies with the httpOnly flag, session hijacking is not possible.

Summary		(es) El punto final de autenticación acepta entrada proporcionada por el usuario sin aplicar las restricciones de validación esperadas, lo que lleva a una falta de codificación de salida adecuada. Esto permite la inyección de cargas útiles JavaScript maliciosas, lo que habilita cross-site scripting reflejado. Un atacante puede aprovechar esta vulnerabilidad para redirigir el navegador del usuario a un sitio web malicioso, modificar la interfaz de usuario de la página web, recuperar información del navegador o causar otras acciones dañinas. Sin embargo, debido a la protección de las cookies relacionadas con la sesión con la bandera httpOnly, el secuestro de sesión no es posible.
