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

Rescanned at commit 8cee08b1681c, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    skills/kafka-python-client/references/common-template.py, line 143 resp = requests.get(url, auth=auth, timeout=timeout)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    skills/kafka-python-client/SKILL.md, line 106 ├── .env.example

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

  • SECRETS_ENV_READ Note

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

    skills/kafka-python-client/references/common-template.py, line 52 config["API_KEY"] = os.environ.get("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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Pass

    No shell or command call was found in the code. This check does not read permissions an entry declares. A permission line to run shell commands and write or edit files was found in this repository, and it may apply to this entry.

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address.
