CVE-2026-49827

WebErpMesv2 is a Resource Management and Manufacturing execution system Web for industry. Versions 1.19 and prior allow any self-registered user to upload arbitrary PHP files through the HR Expense scan_file parameter, leading to Remote Code Execution. Combined with open registration (no invite required) and broken role middleware (CheckUserRole silently swallows RouteNotFoundException), this chain is effectively unauthenticated RCE against any default installation. The issue is patched in commit 5c54862fa044b363fd2be03d586750e81afd6818.

Summary		(es) WebErpMesv2 es un sistema web de gestión de recursos y ejecución de fabricación para la industria. Las versiones 1.19 y anteriores permiten a cualquier usuario autorregistrado subir archivos PHP arbitrarios a través del parámetro scan_file de HR Expense, lo que lleva a la ejecución remota de código. Combinado con el registro abierto (no se requiere invitación) y un middleware de rol defectuoso (CheckUserRole ignora silenciosamente RouteNotFoundException), esta cadena es efectivamente una RCE no autenticada contra cualquier instalación por defecto. El problema está parcheado en el commit 5c54862fa044b363fd2be03d586750e81afd6818.
