Executive Summary

This vulnerability affects the Craft platform, specifically versions from 5.0.0-RC1 to 5.8.21. It is a stored Cross-Site Scripting (XSS) issue that occurs via Entry Type names.

This can lead to unauthorized actions, data theft, session hijacking, or other malicious activities depending on the attacker's intent and the privileges of the affected users.
