Description

OpenClaw before 2026.3.24 contains an incomplete fix for CVE-2026-27486 where the !stop chat command uses an unpatched killProcessTree function from shell-utils.ts that sends SIGKILL immediately without graceful SIGTERM shutdown. Attackers can trigger process termination via the !stop command, causing data corruption, resource leaks, and skipped security-sensitive cleanup operations.
