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.
Rescanned at commit 3e5c92859ec2, unchanged since the check below.
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.
e2e/run_script_e2e_test.go, line 85
"script": "curl http://example.com", - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
e2e/run_script_e2e_test.go, line 85
"script": "curl http://example.com", - SECRETS_PATH_DOTENV Low
Mentions a .env file.
scripts/jules_submit.py, line 23
# Config - loads API key from .env.local or .env (never hardcode secrets) - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
cmd/osmcp/init_test.go, line 17
cmd := exec.Command("go", "build", "-o", "osmcp_test_bin", ".") - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
scripts/jules_submit.py, line 28
key = os.environ.get("JULES_API_KEY")
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.
