Compatibility: Not stated.
Grade B
Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
mcp/scripts/smoke.ts, line 33
ok((await fetch(url)).status === 405, "GET returns 405"); - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
mcp/scripts/smoke.ts, line 33
ok((await fetch(url)).status === 405, "GET returns 405"); - SECRETS_PATH_DOTENV Low
Mentions a .env file.
docs/releases/v2.4.0.md, line 62
- Security: a plaintext `.env` or credential file in a workspace an agent can read counts - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
scripts/check_public_commit.py, line 24
return subprocess.run( - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
mcp/scripts/check-bundle.mjs, line 22
process.env.FLOW_TOKEN_KEYS = `1:${randomBytes(32).toString("base64")}`;
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.
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.
