AI Security Review
scanned 2d ago · by lpm-firewall-aiNo fixed gateway or install-time exfiltration path was found. The repository reader can nevertheless forward an Authorization header across a host-changing redirect, a credential-handling vulnerability that warrants a warning but does not establish malicious intent.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user-run CLI operation reads a repository file using a token, and the repository endpoint responds with a redirect to another host.
Impact
The redirect destination may receive the repository token.
Mechanism
The reader follows the response Location while reusing the original headers, including Authorization.
AI rationale
No fixed gateway or install-time exfiltration path was found. The repository reader can nevertheless forward an Authorization header across a host-changing redirect, a credential-handling vulnerability that warrants a warning but does not establish malicious intent.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Critical Vulnerability with medium false-positive risk.
Evidence for warning
- Authenticated repository reads can use environment, git credential, or GitHub CLI tokens.
- The HTTP reader follows redirect locations without removing the original request headers, which can forward Authorization to another host.
- The package exposes a CLI entry point; the flagged network and process behavior is in that tool’s repository-reading path.
Evidence against
- The manifest has no install, preinstall, or postinstall hook.
- The GitHub token strategy is associated with repository reads; I found no fixed unofficial gateway or credential persistence behavior.
- The redirect issue requires an authenticated repository read to receive a redirect to another host; the source does not show a fixed attacker-controlled destination.
