GHSA-66Q4-VFJG-2QHH Claude Code Vulnerable to Command Injection via Directory Change Bypasses Write Protection

Claude Code failed to properly validate directory changes when combined with write operations to protected folders. By using the cd command to navigate into sensitive directories like .claude, it was possible to bypass write protection and create or modify files without user confirmation. Reliabl...

CVE-2026-25725

Claude Code is an agentic coding tool. Prior to version 2.1.2, Claude Code's bubblewrap sandboxing mechanism failed to properly protect the .claude/settings.json configuration file when it did not exist at startup. While the parent directory was mounted as writable and .claude/settings.local.json...

CVE-2026-25724

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...

CVE-2026-25724

Claude Code has a permission-deny bypass flaw via symbolic links. Prior to version 2.1.7, if access to a file (e.g., /etc/passwd) was denied but Claude Code could reach a symlink to that file, the tool could read the restricted file without enforcing the deny rule. The issue has been patched in v...
