Title source: llm
STIX 2.1

Description

CKEditor4 is an open source what-you-see-is-what-you-get HTML editor. A theoretical vulnerability has been identified in CKEditor 4.22 (and above). In a highly unlikely scenario where an attacker gains control over the https://cke4.ckeditor.com domain, they could potentially execute an attack on CKEditor 4 instances. The issue impacts only editor instances with enabled version notifications. Please note that this feature is disabled by default in all CKEditor 4 LTS versions.
