Unauthenticated Arbitrary File Read in Meshery

Publication date: 2026-07-23

Last updated on: 2026-07-23

Assigner: VulnCheck

Description
Meshery before 1.0.57 contains an unauthenticated arbitrary file read vulnerability in the /api/system/fileView and /api/system/fileDownload endpoints that pass user-supplied file parameters directly to os.Open without path validation. Attackers can supply absolute paths or traversal sequences in the file parameter to read arbitrary files from the host filesystem without authentication.

Executive Summary

CVE-2026-65919 is an unauthenticated arbitrary file read vulnerability in Meshery versions before 1.0.57. It affects the /api/system/fileView and /api/system/fileDownload endpoints, which accept user-supplied file parameters without proper validation. Attackers can exploit this by providing absolute paths or path traversal sequences to read arbitrary files from the host filesystem without authentication.

Detection Guidance

To detect this vulnerability, check if your Meshery version is before 1.0.57. Use commands like 'meshery version' or inspect the server logs for requests to /api/system/fileView or /api/system/fileDownload endpoints. Test by attempting to access sensitive files via these endpoints with path traversal sequences like '../etc/passwd'.

Impact Analysis

This vulnerability allows attackers to read sensitive files on the server, including configuration files, credentials, or other confidential data. Since the endpoints bypass authentication, any unauthenticated user can exploit this to access restricted files, potentially leading to data breaches or further system compromise.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA by exposing sensitive personal or health data. GDPR requires protecting personal data, while HIPAA mandates safeguarding protected health information. A breach via this vulnerability may result in legal penalties, reputational damage, and loss of trust.

Mitigation Strategies

Immediately upgrade Meshery to version 1.0.57 or later. If upgrading is not possible, restrict access to the vulnerable endpoints by modifying firewall rules or disabling them. Monitor network traffic for suspicious requests to these endpoints.
