CyberRota Analysis

AI-Generated

Genkit is vulnerable due to improper validation of host request headers, allowing any host on the developer's network or any website accessed via DNS rebinding to execute arbitrary actions on the Dev UI server (default port 4000) through the POST /api/runAction endpoint. This could lead to unauthorized access and manipulation of sensitive data or actions within the application. Developers and organizations using Genkit should prioritize applying the patch released on June 18, 2026, to mitigate this high-severity risk.

Original NVD Description

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.
