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

  - DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. Prior to 3.4.7,
    DOMPurify IN_PLACE sanitization could skip shadow contents attached to an element inside
    <template>.content, allowing attacker-controlled markup such as event handlers, JavaScript URLs, or
    scripts to survive and execute when an application cloned and inserted the sanitized template. This issue
    is fixed in version 3.4.7. (CVE-2026-49978)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
