Anthropic said on March 31, 2026 that a public npm release of its Claude Code CLI mistakenly exposed about 512,000 lines of TypeScript via a shipped source map and an accessible archive. The package version 2.1.88 included a 59.8 MB JavaScript source map that pointed to a zip file on the company's Cloudflare R2 bucket, and mirrored copies later spread online.
