The WPForms – Easy Form Builder for WordPress – Contact Forms, Payment Forms, Surveys, & More plugin for WordPress is vulnerable to Improper Neutralization of CRLF Sequences ('CRLF Injection') in all versions up to, and including, 1.10.2 This is due to
get reply to address() processing the Reply-To display name through smart-tag expansion with context 'notification' instead of 'notification-reply-to', which bypasses email-address validation while wpforms sanitize textarea field() intentionally preserves CR/LF characters that are never stripped before the display name is concatenated into the raw Reply-To: mail header string. This makes it possible for unauthenticated attackers to inject arbitrary additional email headers — such as Bcc: — 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.Correção
