CVE-2026-22217

OpenClaw 2026.2.22 < 2026.2.23 - Arbitrary Binary Execution via $SHELL Environment Variable Trusted Prefix Fallback

Published Mar 18, 2026 CVSS 4.0 · 5.8 Medium EPSS < 1% KEV · Not listed
Description
OpenClaw version 2026.2.22 prior to 2026.2.23 contains an arbitrary code execution vulnerability in shell-env that allows attackers to execute attacker-controlled binaries by exploiting trusted-prefix fallback logic for the $SHELL variable. An attacker can influence the $SHELL environment variable on systems with writable trusted-prefix directories such as /opt/homebrew/bin to execute arbitrary binaries in the OpenClaw process context.
