Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    claude-setup/skills/mxKnowledge/scripts/knowledge-cache.js, line 59 try { fs.unlinkSync(tmp); } catch { /* best effort */ }

  • NETWORK_NO_FIXED_HOST Low

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

    admin/www/js/api.js, line 33 const res = await fetch('api' + path, opts);

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    claude-setup/hooks/env-guard.js, line 3 // Rule: values inside .env files (.env, *.env, .env.*) must never reach the

  • SECRETS_ENV_READ Note

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

    src/proxy-go/inbox.go, line 72 sockToken: os.Getenv("CLAUDE_CODE_MESSAGING_TOKEN"),

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    admin/www/js/lib/three.min.js, line 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.

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.
