Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit 8d31a285db78, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/core/auth.ts, line 365 await fs.unlink(configFile);

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    deploy-server.sh, line 149 if curl -s http://localhost:$PORT/health >/dev/null 2>&1; then

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    deploy-server.sh, line 149 if curl -s http://localhost:$PORT/health >/dev/null 2>&1; then

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/rate-limit-tester.cjs, line 26 // Try to load .env file from scripts directory

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    scripts/rate-limit-tester.cjs, line 71 REDDIT_CLIENT_SECRET: process.env.REDDIT_CLIENT_SECRET || 'test_secret',

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.
