CVE-2026-101884
HighCVSS 7.5Summary
OpenClaw Windows Node before version 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.
Risk Assessment
An attacker with gateway or agent access can execute arbitrary code on the Windows host, potentially leading to full system compromise and data theft.
Recommendation
Upgrade OpenClaw Windows Node to version 2026.7.1 or later, which includes a fix blocking dangerous environment variables. Restrict access to gateways and agents.
Other vulnerabilities in OpenClaw Windows Node
See all- CVE-2026-101882High
OpenClaw Windows Node before version 2026.7.1 contains an incomplete validation vulnerability in system.execApprovals.set that accepts wildcard-executable rules and abusable system binaries like mshta, rundll32, and certutil. Remote callers can add broad allow rules to execute arbitrary commands on the Windows host through system.run without operator checks or user prompts.
- CVE-2026-101880High
OpenClaw Windows Node before version 2026.7.1 contains an incorrect authorization vulnerability in the system.run exec-approval policy where ExecShellWrapperParser fails to split commands on pipe operators or extract command substitutions. Connected gateways or agents can bypass approval rules by placing denied commands behind allowed prefixes using pipe operators or command substitution syntax, achieving arbitrary command execution on Windows hosts.
