CVE-2026-48019 is a high-severity CRLF injection flaw in the Laravel framework affecting versions up to 13.9.0 and versions before 12.60.0. The issue is caused by improper neutralization of carriage return and line feed sequences in email validation or handling logic when user-controlled email address input is passed into Laravel’s mail workflow and ultimately to Symfony Mailer and Symfony Mime. In applications that use untrusted email input in features such as registration, password reset, contact forms, or other transactional messaging, specially crafted input containing CRLF sequences can alter the structure of outbound messages and interfere with normal email processing.
