概要

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/backups folder.

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

With those criteria in place, attackers could create a specific, malicious request to the /updater/restore-db endpoint and execute CLI commands remotely. This issue is fixed in versions 4.16.3 and 5.8.4.
