Grade D
Two or more Medium findings, or a High. 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 SECRETS_PATH_CREDENTIAL OBFUSCATION_ENCODED_BLOB OBFUSCATION_MINIFIED_PAYLOAD
Why this grade
- PERMISSION_SHELL_UNDECLARED Medium
Runs shell commands that the manifest or description does not mention.
scripts/smoke.py, line 271
shutil.rmtree(_RUNTIME_DIR, ignore_errors=True) - SECRETS_PATH_CREDENTIAL Medium
Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).
vibatchium/fspolicy.py, line 10
read as ``upload ~/.ssh/id_ed25519``. The MCP server, the REST shim and the SDK - OBFUSCATION_ENCODED_BLOB Medium
Contains a long base64 shaped string in a file that should be readable.
uv.lock, line 1
version = 1 - OBFUSCATION_MINIFIED_PAYLOAD Medium
Contains a very long line with almost no spaces in a script or style file.
uv.lock, line 1
version = 1
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.
What was checked
Plain notes from the hygiene checks.
Permissions
Concern

Install and update
Pass
No install-time script found, and dependencies are pinned or absent.
Network
Concern
can reach a host that is not written as a fixed address. can reach datasets-server.huggingface.co. The description does not name that host.

When WebFetch / WebSearch / curl comes back with any of these, the page is NOT unreachable - it's behind a wall a plain HTTP client can't pass:
Secrets
Concern
reads a credential or environment file.

Agent instructions
Pass
No instruction to ignore earlier instructions or to hide a step.
Obfuscation
Concern
