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 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.

    packages/agent-rider-quickstart/quickstart.mjs, line 33 const res = await fetch(`${LIVE_BASE}${path}`, {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    packages/agent-rider-quickstart/quickstart.mjs, line 33 const res = await fetch(`${LIVE_BASE}${path}`, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .cursor/install.sh, line 5 # - Creates a local dev env file (src/.env.local) with SAFE PLACEHOLDER values

  • SECRETS_ENV_READ Note

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

    packages/agent-rider-quickstart/quickstart.mjs, line 104 const sandboxKey = process.env.RIDER_SANDBOX_KEY || DOCUMENTED_SANDBOX_KEY;

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    src/cuni-bin/cuni, line 1 ELF>�

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.

What was checked

  • Permissions

    Pass

    No shell or command execution found, and no extra permission was declared.

  • Install and update

    Pass
