Anthropic accidentally shipped internal source code in a recent release of its Claude Code tool, prompting developer scrutiny and fresh questions about its security practices.
A spokesperson said the exposure did not include customer data or credentials, and stemmed from a packaging mistake caused by human error rather than a security breach, adding that the company is introducing steps to prevent repeats.
Developers reviewed the leaked code to understand how the coding agent works, and what features might be coming next, while some security experts warned the unintended release could still create vulnerabilities.
The mishap follows another recent leak that exposed thousands of internal files, including draft details of Anthropic’s unreleased Mythos model.
