Anthropic accidentally exposes system behind Claude Code

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 prioritising 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."
