Vulnerability Title
WPForms <= 1.10.2 - Improper Neutralization of CRLF Sequences to Unauthenticated Email Header Injection via Reply-To Display Name
Vulnerability Description
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.

Vulnerability Description
Syed Balkhi WPForms是Syed Balkhi个人开发者的一款WordPress表单构建插件。 Syed Balkhi WPForms 1.10.2及之前版本存在输入验证错误漏洞,该漏洞源于对CRLF序列的中和不当,这是由于`get_reply_to_address()`处理Reply-To显示名称时使用错误的上下文导致绕过电子邮件地址验证,同时`wpforms_sanitize_textarea_field()`保留CR/LF字符,使得未经身份验证的攻击者可以向出站通知电子邮件中注入额外
