Claude Code leak links to Bun bug
A Reddit post in r/LocalLLaMA points to Bun issue #28001 as a possible contributing factor behind the Claude Code source code leak. The thread argues that Bun may have generated or exposed source maps in a way that let Anthropic’s published npm package reveal readable TypeScript source and internal implementation details. The Bun connection is plausible but still speculative, so the safest framing is that this was likely a tooling and release-process failure, with Bun as a suspected upstream factor rather than a confirmed sole root cause.
This looks like a supply-chain/security hygiene failure first, with Bun as a suspected upstream factor rather than a confirmed root cause.
- –The story is about Claude Code, not Bun itself; Bun is the suspected enabler in the build/publish chain.
- –The leak is security-relevant because source maps can expose implementation details, internal paths, feature flags, and other sensitive product logic.
- –The Reddit framing is cautious: it cites Bun issue #28001, but does not prove causality.
- –Editorially, this fits best as a security incident/news item rather than a product update.
- –If you publish this, avoid overstating the root cause unless you can verify Anthropic’s internal build path.
