Summary
TinyMCE XSS vulnerability in notificationManager.open API
Details

Impact

A cross-site scripting (XSS) vulnerability was discovered in TinyMCE’s Notification Manager API. The vulnerability exploits TinyMCE's unfiltered notification system, which is used in error handling. The conditions for this exploit requires carefully crafted malicious content to have been inserted into the editor and a notification to have been triggered.

When a notification was opened, the HTML within the text argument was displayed unfiltered in the notification. The vulnerability allowed arbitrary JavaScript execution when an notification presented in the TinyMCE UI for the current user. This issue could also be exploited by any integration which uses a TinyMCE notification to display unfiltered HTML content.

Patches

This vulnerability has been patched in TinyMCE 5.10.8 and TinyMCE 6.7.1 by ensuring that the HTML displayed in the notification is sanitized, preventing the exploit.

Fix

To avoid this vulnerability:

  • Upgrade to TinyMCE 5.10.8 or higher for TinyMCE 5.x.
  • Upgrade to TinyMCE 6.7.1 or higher for TinyMCE 6.x.
