CVE-2026-29962

HSC MailInspector v5.3.3-7 contains a Local File Inclusion (LFI) vulnerability caused by improper control of user-supplied file paths. The endpoint /vendor/phpunit/phpunit.php processes user-controlled parameters that directly affect file access operations without adequate validation, sanitization, or path restriction. This allows a remote attacker to exploit Path Traversal techniques to read arbitrary files from the underlying operating system and application directories, leading to sensitive information disclosure.

Summary		(es) HSC MailInspector v5.3.3-7 contiene una vulnerabilidad de inclusión local de ficheros (LFI) causada por un control inadecuado de las rutas de ficheros proporcionadas por el usuario. El endpoint /vendor/phpunit/phpunit.php procesa parámetros controlados por el usuario que afectan directamente a las operaciones de acceso a ficheros sin validación, saneamiento o restricción de ruta adecuados. Esto permite a un atacante remoto explotar técnicas de salto de ruta para leer ficheros arbitrarios del sistema operativo subyacente y directorios de la aplicación, lo que lleva a la revelación de información sensible.
