Affected: Homebrew: openclaw-cli

## Summary In affected versions of `openclaw`, browser-originated WebSocket connections could bypass origin validation when `gateway.auth.mode` was set to `trusted-proxy` and the request arrived with proxy headers. A page served from an untrusted origin could connect through a trusted reverse proxy, inherit proxy-authenticated identity, and establish a privileged operator session.

## Impact This issue affects deployments that expose the Gateway behind a trusted reverse proxy and rely on browser origin checks such as `controlUi.allowedOrigins` to restrict browser access. An attacker who can cause a victim browser to load a malicious page that can reach the proxy endpoint could establish a cross-site WebSocket connection and call privileged Gateway methods.

In verified impact, the attacker-origin page was able to request `operator.admin` and successfully call `config.get`, exposing sensitive configuration. Depending on the deployment, the same authenticated operator path could also permit other privileged reads or mutations available to operator-class callers.

## Affected Packages and Versions - Package: `openclaw` (npm) - Affected versions: `< 2026.3.11` - Fixed in: `2026.3.11`

## Technical Details The WebSocket handshake logic treated proxy-delivered requests as exempt from the generic browser origin check whenever an `Origin` header was present alongside proxy headers. In `trusted-proxy` mode, that exemption allowed browser-originated connections to skip the normal orig…

OpenClaw is a personal AI assistant. Prior to 2026.3.11, browser-originated WebSocket connections could bypass origin validation when gateway.auth.mode was set to trusted-proxy and the request arrived with proxy headers. A page served from an untrusted origin could connect through a trusted reverse proxy, inherit proxy-authenticated identity, and establish a privileged operator session. This vulnerability is fixed in 2026.3.11.
