This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the form builder interface. This only affects multi-site installations and installations where unfiltered_html has been disabled."}], "lastModified": "2026-01-29T16:31:35.700", "sourceIdentifier": "security@wordfence.com"}
