medium Tenable Self-Hosted Container Security Plugin ID 440766

Description

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

 - fast-xml-parser allows users to process XML from JS object without C/C++ based libraries or callbacks.
 Prior to version 5.7.0, XMLBuilder does not escape the "-->" sequence in comment content or the "]]>"
 sequence in CDATA sections when building XML from JavaScript objects. This allows XML injection when user-
 controlled data flows into comments or CDATA elements, leading to XSS, SOAP injection, or data
 manipulation. This issue has been patched in version 5.7.0. (CVE-2026-41650)

Solution

Update the fast-xml-parser library and its related packages to version 5.7.0 or later.
