CVE-2026-35667 Details
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.
A vulnerability exists in OpenClaw versions prior to 2026.3.24, where the !stop chat command improperly terminates processes by using an unpatched killProcessTree function from shell-utils.ts. This function sends a SIGKILL signal immediately, without allowing for a graceful shutdown with SIGTERM. As a result, the !stop command can cause data corruption, resource leaks, and bypass important security-related cleanup tasks.
Users can update to OpenClaw version 2026.3.24 or later, where this vulnerability has been patched.
