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 d48afcae6140, unchanged since the check below.
NETWORK_NO_FIXED_HOST PERMISSION_SHELL_DECLARED SECRETS_ENV_READ OBFUSCATION_FILE_CAP_REACHED
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
daemon/webui/src/api.js, line 18
const resp = await fetch(path, { ...opt, headers }); - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
cmd/a2ald/daemon_ensure.go, line 46
cmd := exec.Command(exe, "-data-dir", dataDir, "-api-addr", apiAddr, "-no-open-browser") //nolint:gosec - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
cmd/a2al/global.go, line 24
if v := os.Getenv("A2AL_TOKEN"); v != "" { - OBFUSCATION_FILE_CAP_REACHED Note

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.
