Description
The npm package express-bunker version 6.1.0 includes a postinstall script that unconditionally performs an HTTP GET request to a hardcoded IP address, transmitting package and environment information. This behavior indicates a dependency-confusion attack vector, where internal dependency names may be shadowed by this malicious public package. Installation of this package can lead to full compromise of the host system, with potential exposure of secrets and keys.
