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.
NETWORK_NO_FIXED_HOST OBFUSCATION_ENCODED_BLOB PERMISSION_SHELL_DECLARED
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
scripts/archive_history.py, line 32
def fetch(endpoint): - OBFUSCATION_ENCODED_BLOB Low
Contains a long base64 shaped string in a file that should be readable.
history/femtech-horizonshield-dev-mcp.json, line 1
{ - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
patch22_citability.py, line 55
r = subprocess.run([sys.executable, "-m", "py_compile", tf.name], capture_output=True, text=True)
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.
