Summary
Malicious code in @mrbenty8jf1p9y5/oidc-bind-canary (npm)

The package's postinstall lifecycle script issues an HTTPS request from the installer's machine to a Cloudflare tunnel at wiki-shared-carlos-exempt.trycloudflare.com on path /token-capture. The request is sent with the Host header spoofed to dependabot-api.githubapp.com and with TLS certificate validation disabled (rejectUnauthorized:false), disguising the callout as legitimate GitHub Dependabot traffic. The destination path name (/token-capture) and the disguise mechanics indicate an install-time beacon to an attacker-controlled listener, firing automatically on npm install.
