SCA: security update for TinyMCE, tinymce, tinymce/tinymce (GHSA-v65r-p3vv-jjfv)

medium Tenable Cloud Security Plugin ID 419111

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 and redo functionality. When a carefully-crafted HTML snippet passes the
XSS sanitisation layer, it is manipulated as a string by internal trimming functions before being stored
in the undo stack. If the HTML snippet is restored from the undo stack, the combination of the string
manipulation and reparative parsing by either the browser's native [DOMParser
API](https://developer.mozilla.org/en-US/docs/Web/API/DOMParser) (TinyMCE 6) or the SaxParser API (TinyMCE
5) mutates the HTML maliciously, allowing an XSS payload to be executed. This vulnerability has been
patched in TinyMCE 5.10.8 and TinyMCE 6.7.1 by ensuring HTML is trimmed using node-level manipulation
instead of string manipulation. Users are advised to upgrade. There are no known workarounds for this
vulnerability. (CVE-2023-45818)
