SCA: security update for TinyMCE, tinymce, tinymce/tinymce (GHSA-v626-r774-j7f8)

medium Tenable Self-Hosted Container Security Plugin ID 419098

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 mutation cross-site scripting (mXSS) vulnerability was
 discovered in TinyMCE’s core undo/redo functionality and other APIs and plugins. Text nodes within
 specific parents are not escaped upon serialization according to the HTML standard. If such text nodes
 contain a special character reserved as an internal marker, they can be combined with other HTML patterns
 to form malicious snippets. These snippets pass the initial sanitisation layer when the content is parsed
 into the editor body, but can trigger XSS when the special internal marker is removed from the content and
 re-parsed. his vulnerability has been patched in TinyMCE versions 6.7.3 and 5.10.9. Users are advised to
 upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48219)
