Hi,

The following vulnerability was published for libowasp-antisamy-java.

CVE-2024-23635[0]:
| AntiSamy is a library for performing fast, configurable cleansing of
| HTML coming from untrusted sources. Prior to 1.7.5, there is a
| potential for a mutation XSS (mXSS) vulnerability in AntiSamy caused
| by flawed parsing of the HTML being sanitized. To be subject to this
| vulnerability the `preserveComments` directive must be enabled in
| your policy file. As a result, certain crafty inputs can result in
| elements in comment tags being interpreted as executable when using
| AntiSamy's sanitized output. Patched in AntiSamy 1.7.5 and later.


If you fix the vulnerability please also make sure to include the
