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.

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    hooks/privacy-block.cjs, line 156 try { fs.unlinkSync(filePath); } catch { /* concurrent prune or consume */ }

  • NETWORK_NO_FIXED_HOST Low

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

    skills/engineering/aif-chrome-profile/references/mcp-config-recipes.md, line 86 curl -s http://127.0.0.1:9222/json/version

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    skills/engineering/aif-chrome-profile/references/mcp-config-recipes.md, line 86 curl -s http://127.0.0.1:9222/json/version

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

  • SECRETS_ENV_READ Note

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

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.
