DescriptionCVE.org

Laravel is a web application framework. Prior to versions 12.60.0 and 13.10.0, a CRLF injection vulnerability in Laravel's email validation, in combination with how Symfony Mailer and Symfony Mime handle certain character sequences, may allow an unauthenticated attacker to interfere with outbound email processing in applications that send mail to user-supplied addresses. This issue has been patched in versions 12.60.0 and 13.10.0.

AnalysisAI

CRLF injection in Laravel Framework (CWE-93) enables unauthenticated remote attackers to manipulate outbound email processing in any application that passes user-supplied email addresses to Laravel's mail functions. An attacker who can provide an email address to an application flow - such as registration, password reset, or contact forms - can embed carriage-return/line-feed sequences to inject additional SMTP headers, reroute messages to unintended recipients, or abuse the application's mail infrastructure as an open relay. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the target Laravel application (1) accepts an email address as input from an unauthenticated user, and (2) uses that address as a recipient, sender, CC, or BCC parameter in a subsequent mail dispatch - for example, sending a registration confirmation, password-reset link, or contact-form acknowledgment to the address the user provided. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The vendor-assigned CVSS 8.9 (AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:L) is defensible and internally consistent. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
