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.

Rescanned at commit 943df06e57da.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/blender-live-check.mjs, line 59 fs.rmSync(scratch, { recursive: true, force: true });

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/blender-live-check.mjs, line 45 const socket = net.connect(port, "127.0.0.1", () => { socket.end(); resolve(true); });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/docker-run.sh, line 3 # Load environment variables from .env file if it exists

  • SECRETS_ENV_READ Note

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

    src/index.ts, line 48 const DEFAULT_API_KEY = process.env.API_KEY || "";

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    src/test/3DBenchy.3mf, line 1 PK� UZ����[Content_Types].xml��Kj�0��9�ж�r[(��΢�����FB��

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.
