Claude Code's “Don't Ask Again” File Exposes Passwords and Keys in 1,122 Public Copies on GitHub

The Hacker News

A recent report from software security company Apiiro has revealed that sensitive information, including passwords and API keys, is publicly accessible in 1,122 GitHub repositories. This issue arises from a feature in Claude Code, Anthropic's AI coding assistant, where users can opt to save commands by selecting 'Yes, and don't ask again.' Unfortunately, this also saves any included secrets, making them visible to anyone browsing these public repositories. This exposes developers and organizations to potential security risks, as attackers can easily access these credentials to compromise systems.
