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. The problem arises because the Entry Type names are not properly sanitized when displayed in the Entry Types list, allowing malicious scripts to be stored and executed.

Impact Analysis

The stored XSS vulnerability can allow an attacker to inject malicious scripts into the Entry Type names, which are then executed in the context of users viewing the Entry Types list. 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.
