      <title>CVE-2026-12127 — WPForms &lt;= 1.10.2 - Improper Neutralization of CRLF Sequences to Unauthenticated Email Header Injection via Reply-To Di…</title>

      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; smub WPForms – AI Form Builder for WordPress – Contact Forms, Payment Forms, Survey Form, Quiz &amp;amp; More&lt;/p&gt;
&lt;p&gt;The WPForms – Easy Form Builder for WordPress – Contact Forms, Payment Forms, Surveys, &amp;amp; More plugin for WordPress is vulnerable to Improper Neutralization of CRLF Sequences (&amp;#39;CRLF Injection&amp;#39;) 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 `&amp;#39;notification&amp;#39;` instead of `&amp;#39;notification-reply-to&amp;#39;`, 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.&lt;/p&gt;</description>
