Meshery before 1.0.57 contains an unauthenticated arbitrary file read vulnerability in the /api/system/fileView and /api/system/fileDownload… (CVE-2026-65919)
Meshery versions prior to 1.0.57 have an unauthenticated arbitrary file read vulnerability in the /api/system/fileView and /api/system/fileDownload endpoints. These endpoints improperly handle user-supplied file parameters without validating paths, allowing attackers to read arbitrary files on the host filesystem without authentication.
AI Analysis
Technical Summary
Meshery before version 1.0.57 contains a directory traversal vulnerability (CWE-22) in the /api/system/fileView and /api/system/fileDownload endpoints. The vulnerability arises because user-supplied file parameters are passed directly to the os.Open function without any path validation. This allows unauthenticated attackers to specify absolute paths or traversal sequences to read arbitrary files from the host filesystem.
Potential Impact
An unauthenticated attacker can read arbitrary files on the host system running Meshery, potentially exposing sensitive information. The vulnerability does not allow modification or denial of service but can lead to significant confidentiality breaches.
Mitigation Recommendations
Upgrade Meshery to version 1.0.57 or later, where this vulnerability is fixed. Since the vulnerability is patched in 1.0.57, applying this official fix fully mitigates the issue.
