Summary

Details

The module provides a permission that allows users to configure email templates containing Twig code. This permission was not marked as restricted.

A site administrator might inadvertently grant this permission to less-trusted users. This would allow those users to execute Twig within email templates, and to gain access to functionality and information intended only for highly trusted administrators.

They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
