    Title
    Symfony: Mailjet Mailer Webhook Parser Never Verifies the Configured Secret — Unauthenticated Webhook Event Injection
    Summary
    Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 6.4.40, 7.4.12, and 8.0.12, the Mailjet mailer bridge and LOX24 notifier bridge webhook parsers received configured webhook secrets but did not verify them, allowing unauthenticated POST requests to inject forged Mailjet and LOX24 event payloads. This issue is fixed in versions 6.4.40, 7.4.12, and 8.0.12.
