Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
Rescanned at commit a0e6dfb62002, unchanged since the check below.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_UNCONFIRMED PERMISSION_SHELL_DECLARED
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
docs/USAGE.md, line 9
-http-timeout int timeout (seconds) for remote config fetch (default 10) - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
docs/USAGE.md, line 9
-http-timeout int timeout (seconds) for remote config fetch (default 10) - SECRETS_PATH_UNCONFIRMED Low
The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.
testdata/stdio-server/main.go, line 122
// confirm mcpServers.<name>.env reached the subprocess. - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
oauth.go, line 319
err = exec.Command("xdg-open", rawURL).Start()
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.
