Vulnerability Data
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…

Mitigating Controls (NIST 800-53 r5) AI
Input validation directly requires checking/neutralizing untrusted data such as HTTP headers before they reach browser components.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require proper output encoding and header sanitization to prevent scripting injection.

Security testing catches header-injection issues before release, covering most of the weakness.
Secure development lifecycle mandates input validation and output encoding that directly prevents header-injection flaws.
Application security requirements explicitly call for neutralizing untrusted data in HTTP headers.
Secure architecture principles reduce injection surfaces but do not prescribe header-specific controls.
Secure coding standards require proper escaping or rejection of scripting syntax in HTTP headers.
