Craft CMS has a theoretical bypass for CVE-2025-23209
Pre-requisites:
- Have a compromised security key (https://craftcms.com/knowledge-base/securing-craft#keep-your-secrets-secret)
- Somehow, manage to create an arbitrary file in Craft’s
/storage/backupsfolder.
With those two pieces in place, you could create a specific, malicious request to the /updater/restore-db endpoint to execute CLI commands remotely.
Fixed in https://github.com/craftcms/cms/commit/a19d46be78a9ca1ea474012a10e97bed0d787f57
