Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

Rescanned at commit d6b0fac1e8a5, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    packages/compiler/src/cli.ts, line 271 fs.unlinkSync(filePath);

  • NETWORK_NO_FIXED_HOST Low

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

    apps/docs/functions/_middleware.ts, line 37 const response = await context.env.ASSETS.fetch(markdownUrl.toString(), request);

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    packages/string/src/installer.ts, line 365 // dotfile/dot-directory (.git, .DS_Store, .env, ...), and symlinks (avoids

  • SECRETS_ENV_READ Note

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

    packages/string/src/github-installer.ts, line 107 const token = process.env.GITHUB_TOKEN || process.env.GH_TOKEN;

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.
