CKEditor CVE-2018-9861 Cross Site Scripting Vulnerability

CKEditor is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input.
Note: This issue was previously titled 'Drupal CKEditor Plugin Cross Site Scripting Vulnerability'. The title have been changed to better reflect the vulnerability information.
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 may allow the attacker to steal cookie-based authentication credentials and launch other attacks.
CKEditor version 4.5.10 through 4.9.1 are vulnerable; other versions may also be affected.
