When the Supply-Chain Attack Has No CVE: Inside the Coder Registry Hijack
No CVE, no poisoned package, no vulnerability-feed entry: a 14-hour takeover of Coder's Cloudflare registry pool served malicious modules from the real registry.coder.com domain and harvested cloud, AI, CI/CD and Git credentials.
Blast radius: Exposure is scoped by activity, not by version: anyone who created or updated a template, ran a template dry-run, or deployed a workspace with module caching disabled between 07:35 and 21:45 UTC on Aug 31, 2026. Coder is where enterprises run cloud dev environments and autonomous AI coding agents on their own infrastructure, so the workspace provisioner and the workspaces themselves hold cloud infrastructure keys (AWS, GCP, Azure), AI-tooling keys (Anthropic, OpenAI), CI/CD and Git tokens, and SSH credentials. Coder reports no indication that its own maintained customer data was impacted. Publicly named users of the platform include the U.S. Department of Defense on AWS GovCloud, a U.S. defense-intelligence organization running more than 2,500 developers, Palantir, Dropbox, and a fintech onboarding 15,000 engineers.
