CyberRota Analysis

AI-Generated

The Symfony framework's Mailjet mailer bridge and LOX24 notifier bridge webhook parsers are vulnerable due to a lack of verification for configured webhook secrets, allowing unauthenticated POST requests to inject malicious event payloads. This could lead to unauthorized actions or data manipulation within applications using these components. Developers and organizations utilizing affected versions should prioritize upgrading to the fixed versions (6.4.40, 7.4.12, or 8.0.12) to mitigate potential exploitation.

Original NVD 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.
