SCA: security update for TinyMCE, tinymce, tinymce/tinymce (GHSA-hgqx-r2hp-jr38)

medium Tenable Cloud Security Plugin ID 415734

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - TinyMCE is an open source rich text editor. 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. 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. Users are advised to upgrade. There are no known workarounds for this vulnerability.
 (CVE-2023-45819)
