CVE-2024-38357
A cross-site scripting (XSS) vulnerability was discovered in TinyMCE’s content parsing code.
Does this matter?
Lower severity and a low EPSS score (0.53%). Track it; it rarely justifies an emergency change on its own.
Description
TinyMCE is an open source rich text editor. A cross-site scripting (XSS) vulnerability was discovered in TinyMCE’s content parsing code. This allowed specially crafted noscript elements containing malicious code to be executed when that content was loaded into the editor. This vulnerability has been patched in TinyMCE 7.2.0, TinyMCE 6.8.4 and TinyMCE 5.11.0 LTS by ensuring that content within noscript elements are properly parsed. Users are advised to upgrade. There are no known workarounds for this vulnerability.
