X-ray any shell command — offline. Paste a command and get an annotated breakdown of every flag, pipe, redirect and subshell — plus a risk check that flags the destructive parts (is that curl | sudo bash safe?) and a clean shareable card you can drop into docs, is
Compatibility: Not stated.
Grade D
Two or more Medium findings, or a High finding. Only try it in a sandbox.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
PERMISSION_SHELL_UNDECLARED INSTALL_REMOTE_SCRIPT SECRETS_PATH_CREDENTIAL
Why this grade
- PERMISSION_SHELL_UNDECLARED Medium
Runs shell commands that the manifest or description does not mention.
README.md, line 293
Consume it from any language (`json.loads(subprocess.check_output(["cmdxray","--json",cmd]))` - INSTALL_REMOTE_SCRIPT Medium
Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).
README.md, line 157
$ curl -fsSL https://get.example.sh | sudo bash - SECRETS_PATH_CREDENTIAL Medium
Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).
docs/cmdxray.browser.js, line 2929
"ssh-keygen": ["ssh-keygen -t ed25519 -C [email protected]", "ssh-keygen -R oldhost", "ssh-keygen -y -f id_rsa"],
Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
