  • GHSA-g78h-pf65-46rvEnhanced Image plugin for CKEditor is vulnerable to Cross-site scripting (XSS)2022-05-14ghsa · osvUS

    The Enhanced Image (aka [image2](https://github.com/ckeditor/ckeditor4/tree/master/plugins/image2)) plugin for CKEditor in versions 4.5.10 through 4.9.1; fixed in 4.9.2, and as used in Drupal 8 before 8.4.7 and 8.5.x before 8.5.2 and other products, is vulnerable to cross-site scripting because it allows remote attackers to inject arbitrary web script through a crafted IMG element.

  • DRUPAL-CORE-2018-0032018-04-18vendor · osvUS

    CKEditor, a third-party JavaScript library included in Drupal core, has [fixed a cross-site scripting (XSS) vulnerability](https://ckeditor.com/blog/CKEditor-4.9.2-with-a-security-patch-released/). The vulnerability stemmed from the fact that it was possible to execute XSS inside CKEditor when using the `image2` plugin (which Drupal 8 core also uses). We would like to thank the CKEditor team for patching the vulnerability and coordinating the fix and release process, and matching the Drupal core security window.
