CVE-2026-22217
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.
Does this matter?
Lower severity and a low EPSS score (0.13%). Track it; it rarely justifies an emergency change on its own.
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.
