medium Tenable Self-Hosted Container Security Plugin ID 409892

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - HtmlSanitizer is a .NET library for cleaning HTML fragments and documents from constructs that can lead to
 XSS attacks. The vulnerability occurs in configurations where foreign content is allowed, i.e. either
 `svg` or `math` are in the list of allowed elements. In the case an application sanitizes user input with
 a vulnerable configuration, an attacker could bypass the sanitization and inject arbitrary HTML, including
 JavaScript code. Note that in the default configuration the vulnerability is not present. The
 vulnerability has been fixed in versions 8.0.723 and 8.1.722-beta (preview version). (CVE-2023-44390)
