Sources and claim methodology

Upstream source 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.
