## Technical details

The vulnerability is a Stored/Reflected XSS (CWE-79) in Jodit Editor's rich text editor component that fails to properly sanitize or filter user input. The editor does not completely remove malicious XSS payloads such as `<iframe src="JavaScript: alert (/xss/)">`, allowing attackers to inject arbitrary JavaScript that executes in the context of the application. The attack requires user interaction (opening or viewing the malicious content) but does not require authentication or special network conditions. An attacker can obtain sensitive information through this vulnerability and potentially execute arbitrary actions in the context of the web application.
