Description
OpenClaw version 2026.2.22 prior to 2026.2.23 contain 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.
Analysis
OpenClaw versions prior to 2026.2.23 contain an arbitrary code execution vulnerability in shell-env that allows local attackers with low privileges to execute attacker-controlled binaries by manipulating the $SHELL environment variable through trusted-prefix fallback logic. An attacker who can write to directories like /opt/homebrew/bin can trick OpenClaw into executing malicious binaries in its process context, potentially escalating privileges or compromising system integrity. …
