Hi,
The reported unauthenticated file write and arbitrary file delete vulnerability affects Helix3-based templates only. Since you are using Helix Ultimate Framework 2.2.3, this specific Helix3 vulnerability does not apply to your website.
However, your SP Page Builder 6.2.2 is outdated. We strongly recommend updating it to the latest version, as older releases contain security vulnerabilities that have since been fixed. Please refer to this forum post for details and the recommended cleanup process if your site may have been exposed:
