CWE-404Published: April 10, 2026· Updated: Apr 13, 2026

6.1
CVSS v3.1

Official 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.

Technical Analysis

CVE-2026-35667 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in availability disruption (denial of service), with a CVSS base score of 6.1.

A proof-of-concept (PoC) exploit exists for CVE-2026-35667. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
