AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe install hook performs unconsented mutation of both the consuming project's package manifest and GitHub Copilot instruction surface. That concrete lifecycle behavior meets the block boundary despite no observed credential exfiltration.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
npm installation of the package as a local dependency
Impact
Can alter downstream project automation and direct AI agents to perform commits and pushes.
Mechanism
postinstall rewrites package scripts and generates agent instruction files
Policy narrative
Installing the package invokes postinstall. It locates the consuming project, removes or replaces scripts, installs guideline templates, and generates .github/copilot-instructions.md. Those generated instructions incorporate package-controlled templates that mandate workflow actions including committing and pushing changes. This silently changes a foreign AI-agent control surface during installation.
AI rationale
The install hook performs unconsented mutation of both the consuming project's package manifest and GitHub Copilot instruction surface. That concrete lifecycle behavior meets the block boundary despite no observed credential exfiltration.

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 96.0% confidence with low false-positive risk.
Evidence for policy risk
- postinstall automatically rewrites the consuming project's package.json scripts.
- postinstall installs templates and generates .github/copilot-instructions.md without user command.
- Bundled agent template directs agents to commit and push changes, extending the install-time AI-agent control surface.
Evidence against
- No credential harvesting or network request occurs in the postinstall path.
- Registry network client is confined to explicit sync functionality, not install-time execution.

Affected versions and remediation
This report applies to workflow-agent-cli@2.23.8.
The versions list below shows the verdict for each recorded version.
- Avoid installing workflow-agent-cli@2.23.8. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
