Description

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.

Affected configurations

• sensiolabs symfony (>= 6.4.0 < 6.4.40) • sensiolabs symfony (>= 7.0.0 < 7.4.12) • sensiolabs symfony (>= 8.0.0 < 8.0.12)
