Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

Rescanned at commit 40e6ba512a2f, unchanged since the check below.

NETWORK_NO_FIXED_HOST OBFUSCATION_ENCODED_BLOB PERMISSION_SHELL_DECLARED SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    scripts/install.sh, line 190 for command_name in curl tar mktemp awk sort grep chmod mkdir cp mv rm; do

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

  • PERMISSION_SHELL_DECLARED Note

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

    cli/ubtctl/main_test.go, line 24 build := exec.Command(goTool, "build", "-o", canonical, ".")

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    cli/ubtctl/ai/planner.go, line 59 apiKey := os.Getenv("ANTHROPIC_API_KEY")

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.

What was checked

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network
