發布日:2024/2/7修改日:2024/3/6

描述

### Affected packages The vulnerability has been discovered in the core HTML parsing module and may affect all editor instances that: * Enabled [full-page editing](https://ckeditor.com/docs/ckeditor4/latest/features/fullpage.html) mode, * or enabled [CDATA](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dtd.html#property-S-cdata) elements in [Advanced Content Filtering](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_advanced_content_filter.html) configuration (defaults to `script` and `style` elements). ### Impact A potential vulnerability has been discovered in CKEditor 4 HTML processing core module. The vulnerability allowed to inject malformed HTML content bypassing Advanced Content Filtering mechanism, which could result in executing JavaScript code.
