Summary
OpenClaw Windows Node through 2026.9.4 contains a server-side request forgery vulnerability in the canvas.present capability that bypasses URL risk evaluation enforced by canvas.navigate. Attackers with gateway or agent access can issue canvas.present to make the node's WebView send requests to localhost, private networks, or tailnet services from the user's machine.
Risk Assessment
Unauthorized access to internal resources risk: an attacker can use the node to scan internal networks, access local services, or launch attacks on other systems.
Recommendation
Update OpenClaw Windows Node to a version newer than 2026.9.4 if a patch is available, and restrict gateway and agent access to trusted entities only.
Other vulnerabilities in OpenClaw Windows Node
See all- CVE-2026-101884High
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.
- 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-2026-101881Medium
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.
- 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.
- CVE-2026-101879Medium
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.
