CVE-2025-40904

A Stored HTML Injection vulnerability was discovered in the Smart Polling functionality due to improper validation of an input parameter. An authenticated user with limited privileges can push malicious remote strategies containing HTML tags through the sync. When a victim views the affected remote strategy in the Smart Polling functionality, the injected HTML renders in their browser, enabling phishing and possibly open redirect attacks. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.

Summary		(es) Se descubrió una vulnerabilidad de inyección HTML almacenada en la funcionalidad de Smart Polling debido a una validación incorrecta de un parámetro de entrada. Un usuario autenticado con privilegios limitados puede insertar estrategias remotas maliciosas que contienen etiquetas HTML a través de la sincronización. Cuando una víctima visualiza la estrategia remota afectada en la funcionalidad de Smart Polling, el HTML inyectado se renderiza en su navegador, lo que permite phishing y posiblemente ataques de redirección abierta. La explotación completa de XSS y la revelación directa de información se evitan mediante la validación de entrada existente y la configuración de la Política de Seguridad de Contenido.
