CVE-2026-35667 is a medium-severity vulnerability rated 6.9/10 on the CVSS scale. 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.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
