Short explanation
The Document Gallery WordPress plugin through version 5.1.1 fails to verify signatures on an unauthenticated webhook endpoint when no shared secret is configured, which is the default state, allowing unauthenticated users to replace thumbnail images published for documents.
The lack of protection in the default state allows attackers to manipulate published document thumbnail images without requiring any external authentication.
What should be done?
- Follow vendor advisories
- Check for available updates and patch status
