Why this grade
- INSTALL_UNPINNED Low
Dependencies use a range or git URL with no lockfile.
package.json, line 19
@modelcontextprotocol/sdk - NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
src/index.ts, line 110
res = await fetch(`${API_BASE}/v1/exec`, { - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
src/index.ts, line 11
const API_KEY = process.env.SCRATCHRUN_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.
