Bitwarden CLI Backdoored: Shai-Hulud Returns Through a 93-Minute npm Window
Between 21:57 and 23:30 UTC on April 22, 2026, a malicious @bitwarden/cli@2026.4.0 was live on npm for 93 minutes — long enough to reach CI/CD pipelines, developer workstations, and cloud automation hosts. The payload steals credentials across GitHub, AWS, GCP, and Azure, propagates as a self-replicating npm worm, injects GitHub Actions workflow stealers, and poisons AI coding assistants by injecting an invisible manifesto into shell configuration files. This is the first documented npm supply chain attack executed through Trusted Publishing.
