Pagelayer <= 2.0.7 - Improper Neutralization of CRLF Sequences to Unauthenticated Email Header Injection via 'email'

The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Improper Neutralization of CRLF Sequences ('CRLF Injection') in all versions up to, and including, 2.0.7. This is due to the contact form handler performing placeholder substitution on attacker-controlled form fields and then passing the resulting values into email headers without removing CR/LF characters. This makes it possible for unauthenticated attackers to inject arbitrary email headers (for example Bcc / Cc) and abuse form email delivery via the 'email' parameter granted they can target a contact form configured to use placeholders in mail template headers.
