NVD description
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.52, 6.4.40, 7.4.12, and 8.0.12, Symfony\Component\Mime\Header\ParameterizedHeader validates and encodes parameter values but emits parameter names verbatim, allowing a caller that derives a parameter name from untrusted input to include CRLF or other non-token bytes and inject additional headers into rendered structured mail headers such as Content-Type or Content-Disposition. This issue is reported as fixed in versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12.

Symfony 8.1.10 patches CVE-2026-45070 in the Mime component, which accepted header parameter names with non-token characters. It reaches past Symfony: Laravel's mailer runs on symfony/mime too. If you generate email, upgrade. https://www.scoutapm.com/blog/symfony-8-1-10-mime-header-injection-cve #php #laravel
