Technical Summary
CVE-2026-41193 is a path traversal vulnerability (CWE-22) in FreeScout's module installation feature prior to version 1.8.215. The vulnerability occurs because the application extracts ZIP archives without validating the contained file paths, enabling an authenticated admin user to write files arbitrarily on the server filesystem. This can lead to complete compromise of confidentiality, integrity, and availability of the affected system. The issue is fixed in FreeScout version 1.8.215.
Potential Impact
An authenticated administrator can exploit this vulnerability to write arbitrary files anywhere on the server filesystem, potentially leading to full system compromise including code execution, data corruption, or denial of service. The CVSS score of 9.1 reflects high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade FreeScout to version 1.8.215 or later, where this vulnerability is fixed. Since this is a self-hosted product, administrators must apply the update manually. There is no official vendor advisory provided here, but the version update is the confirmed remediation. Patch status is confirmed by the version fix note.
