CVE-2026-7400: Path Traversal in geekgod382 filesystem-mcp-server
A security vulnerability has been detected in geekgod382 filesystem-mcp-server 1.0.0. This issue affects the function is_path_allowed of the file server.py of the component read_file_tool/write_file_tool. Such manipulation leads to path traversal. The attack can be launched remotely. The exploit has been disclosed publicly and may be used. Upgrading to version 1.1.0 is capable of addressing this issue. The name of the patch is 45364545fc60dc80aadcd4379f08042d3d3d292e. Upgrading the affected component is advised.
AI Analysis
Technical Summary
The vulnerability in geekgod382 filesystem-mcp-server 1.0.0 arises from insufficient validation in the is_path_allowed function of server.py, enabling path traversal attacks. This allows remote attackers to potentially read or write files outside intended directories by manipulating file paths. The vulnerability is fixed in version 1.1.0, with the patch identified by commit 45364545fc60dc80aadcd4379f08042d3d3d292e. The CVSS 4.0 base score is 6.9, indicating a medium severity with network attack vector, low complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to unauthorized access to files on the server, potentially exposing sensitive data or allowing unauthorized file modifications. The vulnerability can be exploited remotely without authentication or user interaction. The impact is limited but significant enough to warrant an upgrade.
Mitigation Recommendations
Upgrading the filesystem-mcp-server to version 1.1.0 is the recommended remediation, as this version contains the official patch addressing the path traversal vulnerability. No other mitigation or temporary workaround is indicated. Users should apply the upgrade promptly to prevent exploitation.
