Rescanned at commit 1d3e13f0f813, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

    Contains a call that can delete files.

    tbank_mcp/skills_cli.py, line 49 shutil.rmtree(old)

  • NETWORK_NO_FIXED_HOST Low

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

    tbank_mcp/checkout.py, line 168 const r = await fetch(url, Object.assign({}, opts || {}, {signal: c.signal}));

  • SECRETS_ENV_READ Note

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

    tbank_mcp/login_cli.py, line 110 if os.environ.get("TBANK_PASSWORD"):

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    tbank_mcp/client.py, line 1 """T-Bank mobile API client - self-bootstrapping, fully headless after login.

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.
