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

Rescanned at commit 9ff9b956ea74, unchanged since the check below.

OBFUSCATION_RUNS_ENCODED_PAYLOAD INSTALL_REMOTE_SCRIPT

Why this grade

  • OBFUSCATION_RUNS_ENCODED_PAYLOAD High

    Decodes and runs an encoded payload (for example eval with atob or base64).

    crates/orion-server/CHANGELOG.md, line 1 # Changelog

  • INSTALL_REMOTE_SCRIPT Medium

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    .github/workflows/release.yml, line 87 run: "curl --proto '=https' --tlsv1.2 -LsSf https://github.com/axodotdev/cargo-dist/releases/download/v0.31.0/cargo-dist-installer.sh | sh"

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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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

Plain notes from the hygiene checks.

  • Permissions

    Pass

    No shell or command execution found, and no extra permission was declared.

  • Install and update

    Serious

    install fetches a script from the network. The docs document an installer that pipes a download into a shell.

  • Network

    Concern

    can reach a host that is not written as a fixed address.

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_PATH_DOTENV

    .gitignore, line 39

    # Environment & local config

    .gitignore, line 40

    .env

  • Agent instructions

    Pass

    No instruction to ignore earlier instructions or to hide a step.

  • Obfuscation

    Serious

    runs an encoded payload.
