CVE-2026-1493

LEX Baza Dokumentów is vulnerable to DOM-based XSS in "em" cookie parameter. The application unsafely processes the parameter on the client side, allowing an attacker to execute arbitrary JavaScript in the context of the victim's browser. An attacker with ability to set a cookie can perform a more severe attack, so we evaluate the impact and risk of exploitation as minimal. However, the vendor considered this a vulnerability and released a security patch. This issue was fixed in version 1.3.4.

Summary		(es) LEX Baza Dokumentów es vulnerable a XSS basado en DOM en el parámetro de cookie ’em’. La aplicación procesa de forma insegura el parámetro en el lado del cliente, permitiendo a un atacante ejecutar JavaScript arbitrario en el contexto del navegador de la víctima. Un atacante con la capacidad de establecer una cookie puede realizar un ataque más grave, por lo que evaluamos el impacto y el riesgo de explotación como mínimos. Sin embargo, el proveedor consideró esto una vulnerabilidad y lanzó un parche de seguridad. Este problema se solucionó en la versión 1.3.4.
