Description Michael Kaplan 2020-03-23 15:22:41 UTC

In CKEditor prior CKEditor 4.14, in HTML data processor function was possible to execute XSS inside CKEditor by persuading the victim to: (1.) switch CKEditor to source mode, then (2.) paste a specially crafted HTML code, prepared by the attacker, into the opened CKEditor source area, and (3.) switch back to WYSIWYG mode or paste specially crafted HTML code into CKEditor in WYSIWYG mode
