What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

OpenClaw versions before 2026.8.1 contain a command parser vulnerability where escaped newlines confuse exec allowlist parsing, allowing hidden commands to execute. Attackers can craft input with escaped newlines to bypass allowlist validation and execute additional commands without expected authorization prompts.
