Does this vulnerability allow unauthenticated remote code execution?

No. Exploitation, as described, requires valid administrative access to OpenMetadata or compromise of an administrator account that can influence FreeMarker template inputs.

What level of access does an attacker need to exploit this issue?

The attacker must have administrative privileges within OpenMetadata or equivalent access to configuration or features that control data rendered in FreeMarker email templates.

What is the safest general fix pattern for this type of issue?

The most robust fix is to treat templates as static and data as untrusted: restrict FreeMarker's capabilities, expose only minimal, pre-sanitized data models to templates, and ensure that any administrator-controlled content is inserted as escaped text rather than executable template logic.
