Ckeditor Ckeditor

CVE-2020-27193

A cross-site scripting (XSS) vulnerability in the Color Dialog plugin for CKEditor 4.15.0 allows remote attackers to run arbitrary web script after persuading a user to copy and paste crafted HTML code into one of editor inputs.

What this means for your business

  • It affects Ckeditor. It matters if your company, or a supplier that handles your data, runs it.
  • An attacker can use it remotely, over a network, without a login, but only after tricking someone into an action such as opening a file or a link.

What to do

  1. 1Check whether your company or your suppliers run Ckeditor, and which version. The affected versions are listed further down this page.
  2. 2If you do, apply the vendor's fix. A patch or vendor advisory has been published.
