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

Rescanned at commit 81c5ba8008fd, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    src/clientFactory.ts, line 42 async fetch(input: Request | URL | string, init?: RequestInit) {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/main.ts, line 87 dotenv.config({ path: path.resolve(dirname, '../.env') });

  • SECRETS_ENV_READ Note

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

    src/input.ts, line 54 if (typeof input.headers === 'object' && !('Authorization' in input.headers) && process.env.APIFY_TOKEN) {

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    package-lock.json, line 1 {

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.
