This makes it possible for unauthenticated attackers to inject arbitrary additional email headers \u2014 such as `Bcc:` \u2014 into outgoing notification emails, silently blind-copying all notification email copies to an attacker-controlled address. Exploitation requires that a form notification is configured to use a Paragraph Text (textarea) field as the Reply-To display name via a Smart Tag."}], "lastModified": "2026-07-01T13:56:17.493", "sourceIdentifier": "security@wordfence.com"}
