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.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
packages/core/src/embeddings.ts, line 65
const res = await fetch("https://api.openai.com/v1/embeddings", { - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
packages/core/src/embeddings.ts, line 65
const res = await fetch("https://api.openai.com/v1/embeddings", { - SECRETS_PATH_DOTENV Low
Mentions a .env file.
packages/cli/src/index.ts, line 50
// Load a .env (vault root, then cwd) so an embedding key need not be exported. - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
packages/cli/src/index.ts, line 277
if (!process.env.OPENAI_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.
