Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST PERMISSION_SHELL_DECLARED
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
chrome_extension/background.js, line 26
const response = await fetch(`${BRIDGE_URL}/api/ext/result`, { - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
chrome_extension/background.js, line 26
const response = await fetch(`${BRIDGE_URL}/api/ext/result`, { - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
benchmarks/latency.py, line 13
process = subprocess.Popen([str(binary)], stdin=subprocess.PIPE, stdout=subprocess.PIPE,
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.
