    Genkit does not properly validate host request headers. Any host on the developer's network, and any website the developer visits (via DNS rebinding), can reach POST /api/runAction on the Dev UI server (default port 4000) and execute any registered Genkit action and read the result. Fixed on 2026-06-18.
