AI Security Review
scanned 26d ago · by lpm-firewall-aiThe install hook automatically retrieves an opaque executable, which the package CLI later runs. The source shows a project-aligned GitHub endpoint and no install-time execution of the downloaded file, so the unresolved payload merits a warning rather than a block.
Decision evidence
public snapshot- The package runs scripts/postinstall.mjs automatically during installation.
- The postinstall downloads a platform-specific executable from the project's GitHub releases and writes it into the package bin directory.
- The CLI shim runs that downloaded executable when invoked; its contents are not present for source inspection.
- The inspected postinstall source downloads and stores the executable but does not execute it during installation.
- The download host and release path match the package's project.
