Malicious code in bjm-low-code-components (npm)

Details

**Severity:** Critical

**Affected versions:** `= 99.0.0`

On npm install, the package's postinstall hook runs canary.js, which collects the installer's hostname, username, current working directory, and selected environment variables and POSTs them over plain HTTP to a hardcoded Burp Collaborator OAST subdomain at 2pslbvbc3adfni1pbe9xy2b1asgj4cs1.oastify.com/bjm-canary. This is a dependency-confusion / reconnaissance beacon: installer-side identity and environment data leave the machine automatically on install to an attacker-controlled endpoint.
