Should you act?

  • Only if you depend on one of the packages below, directly or transitively, in a vulnerable version. Check your lockfile with npm audit (or: npm ls <package>).
  • No CVE has been assigned, so it will not appear in CVE-based scanners that ignore GitHub advisories. npm audit, pip-audit and Dependabot do read GitHub advisories.

Impact

On April 30, 2026, version 7.0.4 of intercom-client was published to npm using credentials obtained from a compromised developer account. This version was not produced by Intercom's build pipeline.

The malicious version contained an obfuscated JavaScript payload that executed during package installation via a preinstall hook. The payload harvested credentials from the environment in which it ran, including cloud provider credentials (AWS, GCP, Azure), environment variables, .env files, GitHub and npm tokens, SSH keys, local configuration files, and cloud metadata service credentials.

Harvested data was exfiltrated to attacker-controlled GitHub repositories. The package was live on npm for approximately 2 hours (15:00-17:00 UTC).

This compromise is part of the "Mini Shai-Hulud" supply chain campaign tracked by Wiz and Socket.

Developers can check if their projects are affected by running: npm list intercom-client. If it shows 7.0.4, the project is affected.

Patches

Version 7.0.3 and all prior versions are unaffected. Downgrade to 7.0.3 immediately.
