Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit c9b5c590b5e6, unchanged since the check below.

NETWORK_NO_FIXED_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.

    rust/src/defs.rs, line 439 assert!(def("a.rs", "fetch", "pub async fn fetch() {}").is_some());

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    bench/posix.py, line 33 return subprocess.call([bash, str(script), *sys.argv[2:]])

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.
