OpenClaw Windows Node before 2026.7.1-3 Missing Authorization

OpenClaw Windows Node before 2026.7.1-3 contains a missing authorization vulnerability in NodeService capture handlers that allows connected gateways or agents to perform screen snapshots, camera snaps, and location captures without consent prompts. Attackers can invoke screen.snapshot, camera.snap, and location.get over the node WebSocket to silently capture screenshots, photograph users through webcams, and obtain device geolocation without user interaction.

OpenClaw Windows Node before 2026.7.1 Authorization Bypass

OpenClaw Windows Node before 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.

OpenClaw Windows Node before 2026.7.1 Denial of Service

OpenClaw Windows Node before 2026.7.1 contains an allocation of resources without limits vulnerability in the gateway WebSocket transport that allows connected gateways to exhaust node memory. Attackers can send an unending sequence of WebSocket continuation frames without EndOfMessage to cause unbounded memory growth until the node process crashes.

OpenClaw Windows Node before 2026.7.1 Remote Code Execution via Environment Override

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.
