Highest confirmed finding severity

Critical

1 confirmed security finding requires attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Most static findings are Markdown examples, defensive security guidance, or documented Higgsfield workflow references rather than active malicious code. One critical issue is confirmed: SKILL.md instructs agents to run a remote installer through the shell, which is unsafe without pinning, verification, and explicit user approval.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 Critical
SKILL.md:81
Pipe to shell pattern
curl -fsSL https://raw.githubusercontent.com/higgsfield-ai/cli/main/install.sh | sh
The skill instructs agents to pipe a remote GitHub installer directly into sh. This executes unaudited network code in the user shell and could compromise the environment if the upstream script changes.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Critical
    Remote installer is piped directly to the shell.
    Replace the command with a pinned release, checksum or signature verification, and explicit user confirmation before installation.
  2. FIX-002
    Medium
    The workflow requires broad local shell and deployment actions.
    Document the exact commands that may run and require confirmation before installs, deletes, secret changes, and production deploys.
  3. FIX-003
    Low
    Documentation examples contain many dangerous pattern names and external URLs.
    Label examples as non-executable guidance and keep risky strings inside clearly marked security reference sections.
