Summary
TinyMCE Cross-Site Scripting (XSS) vulnerability using noneditable_regexp option
Details

Impact

A cross-site scripting (XSS) vulnerability was discovered in TinyMCE’s content extraction code. When using the noneditable_regexp option, specially crafted HTML attributes containing malicious code were able to be executed when content was extracted from the editor.

Patches

This vulnerability has been patched in TinyMCE 7.2.0, TinyMCE 6.8.4 and TinyMCE 5.11.0 LTS by ensuring that, when using the noneditable_regexp option, any content within an attribute is properly verified to match the configured regular expression before being added.

Fix

To avoid this vulnerability:

  • Upgrade to TinyMCE 7.2.0 or higher.
  • Upgrade to TinyMCE 6.8.4 or higher for TinyMCE 6.x.
  • Upgrade to TinyMCE 5.11.0 LTS or higher for TinyMCE 5.x (only available as part of commercial long-term support contract).
