CVE-2026-25724

Claude Code Has Permission Deny Bypass Through Symbolic Links

Published: Feb 6, 2026Updated: Feb 9, 2026 Sources: CVE List NVD GHSACWE-61

7.5HIGH

Description

Claude Code is an agentic coding tool. Prior to version 2.1.7, Claude Code failed to strictly enforce deny rules configured in settings.json when accessing files through symbolic links. If a user explicitly denied Claude Code access to a file (such as /etc/passwd) and Claude Code had access to a symbolic link pointing to that file, it was possible for Claude Code to read the restricted file through the symlink without triggering deny rule enforcement. This issue has been patched in version 2.1.7.
