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/sandbox/src/index.ts, line 234
await fs.rm(this.#directory, { recursive: true, force: true }); - NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
packages/providers/src/index.ts, line 46
const response = await fetch(this.options.endpoint, { - SECRETS_PATH_DOTENV Low
Mentions a .env file.
.gitignore, line 5
.env - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
apps/cli/src/main.ts, line 365
detail: process.env.MODEL_API_KEY
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.
