What an attacker can do
The source says when Twig content processing is enabled (twig_content.process_enabled: true), an attacker with page-write API permission can use Twig's string concatenation operator (~) to dynamically construct event handler names, dangerous tag names, or dangerous protocols at render time (e.g. {% set x = "on" ~ "error" %}). Vendor/CNA’s CVSS 4.0 assessment (base score 5.1/10) rates confidentiality, integrity and availability impact as none.
