CWE
  • CWE-184 - Incomplete List of Disallowed Inputs
Summary
OpenClaw Windows Node before 2026.7.1 contains an incomplete environment-variable sanitizer in system.run that fails to block GIT_CONFIG_*, DOTNET_STARTUP_HOOKS, and JAVA_TOOL_OPTIONS variables. Attackers with gateway or agent access can supply these variables to allowlisted tools like git, dotnet, or java to load attacker-controlled code and achieve arbitrary code execution.
