| Doc Text: |
A flaw was found in Claude Code, an agentic coding tool, in its handling of worktrees. This vulnerability allowed the creation of specially named worktrees and navigation outside of the intended secure environment, leading to what is known as a 'git directory confusion attack'. By manipulating symbolic links and how git monitors file system changes, an attacker could overwrite important user files, potentially leading to unauthorized code execution on the user's system. This attack requires a user to interact with a malicious code repository.
