What it is

The Bold Page Builder WordPress plugin before 5.9.8 does not properly validate a link URL before outputting it in an HTML attribute, relying on a filter that can be evaded, allowing users with the Contributor role and above to inject arbitrary web scripts that execute when a user clicks the affected link.
