PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    packages/berth/src/utils/cache.ts, line 67 await fs.unlink(getCachePath(key));

  • NETWORK_NO_FIXED_HOST Low

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

    packages/aware/src/fragments/framework/nextjs-14.ts, line 37 - **\`fetch()\` is cached by default in Next 14** (\`{ cache: 'force-cache' }\` is the default)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    packages/aware/src/detectors/database.ts, line 11 // 2. Check .env DATABASE_URL

  • SECRETS_ENV_READ Note

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

    packages/envalid/scripts/post-pr-comment.mjs, line 32 const token = process.env.GITHUB_TOKEN;

  • OBFUSCATION_FILE_CAP_REACHED Note

    The 400 file cap was reached before every file was read.

    packages/envalid/tests/utils/strings.test.ts, line 1 import { describe, it, expect } from "vitest";

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.
