CVE-2024-38356

TinyMCE is an open source rich text editor. 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. 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. Users are advised to upgrade. There are no known workarounds for
this vulnerability.
