This affects development mode only.\nApps without a configured [`allowedDevOrigins`](https://nextjs.org/docs/app/api-reference/config/next-config-js/allowedDevOrigins) still allow connections from any origin.\n\n## Patches\nFixed by validating `Origin: null` through the same cross-site origin-allowance checks used for other origins.  \n\n## Workarounds\nIf upgrade is not immediately possible:\n- Do not expose `next dev` to untrusted networks.\n- Block websocket upgrades to `/_next/webpack-hmr` when `Origin` is `null` at your proxy.",

Starting in version 16.0.1 and prior to version 16.1.7, in `next dev`, cross-site protection for internal websocket endpoints could treat `Origin: null` as a bypass case even if `allowedDevOrigins` is configured, allowing privacy-sensitive/opaque contexts (for example sandboxed documents) to connect unexpectedly. If a dev server is reachable from attacker-controlled content, an attacker may be able to connect to the HMR websocket channel and interact with dev websocket traffic. This affects development mode only. Apps without a configured `allowedDevOrigins` still allow connections from any origin. The issue is fixed in version 16.1.7 by validating `Origin: null` through the same cross-site origin-allowance checks used for other origins. If upgrading is not immediately possible, do not expose `next dev` to untrusted networks and/or block websocket upgrades to `/_next/webpack-hmr` when `Origin` is `null` at the proxy.",
