Anthropic Accidentally Exposes Source Code for Claude Code

Source Domain: www.cnet.com

The source code for Anthropic’s coding tool, Claude Code, was accidentally disclosed when the company uploaded version 2.1.88, including an inadvertent source map file.
The leak exposed over 500,000 lines of code across nearly 2,000 files, which gained significant attention after being shared by a security researcher on X.
The leaked source code gave developers insight into Anthropic’s product roadmap and could allow competitors to understand the tool’s architecture.
An Anthropic spokesperson confirmed the leak resulted from human error, and emphasized that no customer data or credentials were exposed.
Despite the leak, the popularity of Claude Code has increased, highlighted by a viral moment during the holidays and a Super Bowl ad campaign against rival company, OpenAI.
