Hi there!
Thanks for reaching out.
Could you please let us know which version of SP Page Builder you are currently using?
Kindly check this post:

If you are using SP Page Builder 5.x, you can apply the security patch and manual fix mentioned there. However, if you are using SP Page Builder 3.x or 4.x, the patch is not required.
In any case, it would be a good idea to run a security check on your website to ensure everything is safe.
Hope this helps!
Best regards,
