## Technical details

The vulnerability is a stored XSS flaw affecting at least 11 endpoints across ALO Suite (CVE-2026-108050 through CVE-2026-108060) where fields including "Nombre", "ReferenceOtherParty", "Codigo", "NombrePF", and "Observaciones" lack proper input sanitization and output encoding. An authenticated attacker can inject malicious scripts into these fields via endpoints such as '/CuentasCorrientes/Create', '/Familias/Edit/{id}', and '/Trabajadores/Create'; when other authenticated users view the stored data, the JavaScript executes in their browser context, allowing session hijacking or unauthorized actions.
