The Grand Restaurant WordPress theme for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 7.0 via deserialization of untrusted input. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

Not sure which version you run? Run a passive check — it reads public files only.

Remediation & mitigations

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
