How CVE-2025-48476 Works
FreeScout versions before 1.8.180 fail to validate user-supplied input in the `fill()` method when editing user records. Attackers with edit permissions can exploit mass-assignment to inject a malicious `password` field into the request payload. The system processes this unchecked input, allowing unauthorized password changes. Once the password is overwritten, attackers gain full account access. The vulnerability stems from missing server-side validation, enabling privilege escalation.
