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...

CVE-2026-25723

Claude Code prior to 2.0.55 allowed command validation bypass by piping sed via echo, enabling writes to the .claude directory and paths outside the project when the attacker could run commands with the "accept edits" feature enabled. The issue has been patched in 2.0.55. Affected software: Claud...

CVE-2026-25722

CVE-2026-25722 affects Claude Code prior to version 2.0.57. The root cause is improper validation of directory changes during write operations to protected folders, allowing an attacker to use the cd command to navigate to sensitive directories (e.g., .claude) and bypass write protections to crea...
