create-vercel-integrationnpm
Advisory published Updated
create-vercel-integration is a confirmed malicious npm package (MAL-2026-5894) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in create-vercel-integration (npm)
What this malware does
Package name mimics Vercel's official create-* initializer convention (e.g. create-next-app), targeting developers who mistype or guess the initializer name and invoke npx create-vercel-integration. The bin script (bin/run.js) hardcodes a callback URL https://deepbounty.dd06-dev.fr/cb/f7506d76-f300-4c91-a105-41c07ad317fc and, on invocation, reads the INIT_CWD environment variable, extracts its basename, and POSTs {pkg, timestamp, transport, project} to that author-controlled endpoint. The package self-describes as a 'Bug Bounty PoC,' but it is published on the public npm registry under a name shaped like an official Vercel scaffold and silently leaks the installer's project directory name to a third party with no disclosure or opt-out. The package provides no legitimate Vercel-integration scaffolding functionality; the bin's only effect is the beacon.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for create-vercel-integration (version 1.0.0).
If you installed it — respond
create-vercel-integration is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If create-vercel-integration was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks create-vercel-integration-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
