Summary
Claude Code, an agentic coding tool, failed to strictly enforce deny rules set in settings.json when accessing files through symbolic links. A user's explicit denial of a file such as /etc/passwd could be bypassed by reading that file through a symlink pointing to it. The issue is tracked as CVE-2026-25724 and affects versions prior to 2.1.7.
Mitigation
This issue has been patched in version 2.1.7.
