CVE-2023-29449 – Limited control of resource utilization in JS preprocessing
https://notcve.org/view.php?id=CVE-2023-29449
JavaScript preprocessing, webhooks and global scripts can cause uncontrolled CPU, memory, and disk I/O utilization. Preprocessing/webhook/global script configuration and testing are only available to Administrative roles (Admin and Superadmin).
