CKEditor 5 is a modern JavaScript rich-text editor with an MVC architecture. From 45.0.0 until 47.7.4 and 48.5.1, the engine uses a vulnerable es-toolkit version whose prototype-pollution behavior can be reached while CKEditor processes incoming style attribute values. Crafted editor content can thereby cause unauthorized JavaScript execution in the browser. This issue is fixed in versions 47.7.4 and 48.5.1.

 https://db.gcve.eu/vuln/ghsa-rh54-vffm-5fvp GHSA-rh54-vffm-5fvp — CKEditor: Cross-site scripting (XSS) in the engine package 2026-10-29T13:28:40.946724+00:00

Affected: npm: ckeditor5, npm: @ckeditor/ckeditor5-engine

### Impact A Cross-Site Scripting (XSS) vulnerability has been discovered in the CKEditor 5 engine. This vulnerability is caused by a prototype pollution issue in the `es-toolkit` library used in the CKEditor 5 codebase. This vulnerability could lead to unauthorized JavaScript code execution when the editor processes incoming `style` attribute values.

The underlying issue has been patched by the library maintainers, and the fix has been incorporated into CKEditor 5.

### Patches The problem has been recognized and patched. The fix will be available in version `48.5.1` (and above) and `47.7.4` (LTS).
