The Publish Pipeline Is the New Attack Surface: Lessons from the Bitwarden Workflow Incident
On April 22, 2026, a malicious version of @bitwarden/[email protected] was published to npm through a compromise of Bitwarden's own publishing workflow. The exposure window was approximately 93 minutes (5:57 PM to 7:30 PM ET). Bitwarden confirmed the compromise was connected to the ongoing Checkmarx supply chain incident disclosed the same day. End-user vault data, production systems, and the legitimate Bitwarden codebase were not impacted; only users who installed @bitwarden/[email protected] from npm during that narrow window were potentially affected. This post covers what Bitwarden has officially confirmed, the response steps for affected teams, and the broader lesson that CI/CD publishing pipelines are themselves the attack surface.
