How to fix?

Upgrade Debian:unstable symfony to version 7.4.12+dfsg-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream symfony package and not the symfony package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

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.
