CVE-2026-29963

HSC MailInspector 5.3.3-7 has a Path Traversal vulnerability due to improper validation of user-supplied input in the /tap/dw.php endpoint. The text parameter is used to construct file paths without adequate normalization or restriction to a safe base directory. A remote attacker can exploit this flaw to access arbitrary files on the underlying operating system, resulting in unauthorized disclosure of sensitive information.

Summary		(es) HSC MailInspector 5.3.3-7 tiene una vulnerabilidad de salto de ruta debido a una validación inadecuada de la entrada proporcionada por el usuario en el endpoint /tap/dw.php. El parámetro text se utiliza para construir rutas de archivo sin una normalización o restricción adecuada a un directorio base seguro. Un atacante remoto puede explotar esta falla para acceder a archivos arbitrarios en el sistema operativo subyacente, lo que resulta en la divulgación no autorizada de información sensible.
