A security researcher discovered that Anthropic's Claude Code, specifically version 2.1.233, can access sensitive information from .env files even when they are included in .gitignore.

The researcher found that only explicit "Read deny" rules and specific hooks reliably prevented Claude Code from accessing this information, highlighting that standard Git practices are insufficient for protecting secrets from AI agents.
