CVE-2026-65919
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
