Anthropic inadvertently released internal source code behind its popular artificial-intelligence-powered Claude coding assistant, raising questions about the security of an AI model developer that has built its brand on prioritizing safety.
“Earlier today, a Claude Code release included some internal source code. No sensitive customer data or credentials were involved or exposed,” Anthropic said in an emailed statement late Tuesday. “This was a release packaging issue caused by human error, not a security breach.”
The accidental release marked Anthropic’s second security slipup in a matter of days, compromising approximately 1,900 files and 512,000 lines of code related to Claude Code — an agentic coding tool that runs directly inside developer environments. Last week, Fortune separately reported that Anthropic had been storing thousands of internal files on a publicly accessible system, including a draft blog post that detailed an upcoming model known internally as both “Mythos” and “Capybara.”
