CVE-2026-25722
Claude Code Vulnerable to Command Injection via Directory Change Bypasses Write Protection
描述
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. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window. Users on standard Claude Code auto-update received this fix automatically. Users performing manual updates are advised to update to the latest version. About Claude Code thanks hackerone.com/nil221 for reporting this issue!
