At a glance

CVE-2025-39352 is a high-severity Missing Authorization vulnerability in the Grand Restaurant WordPress WordPress theme, affecting versions <= 7.0. It carries a CVSS score of 8.2 (reachable over the network; low attack complexity; high availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed April 2025, reported by Ananda Dhakal.

Vulnerability Overview

The Grand Restaurant WordPress theme for WordPress is vulnerable to unauthorized modification of data that can lead to a denial of service due to a missing capability check on a function in all versions up to, and including, 7.0. This makes it possible for unauthenticated attackers to delete arbitrary option values on the WordPress site. This can be leveraged to delete an option that would create an error on the site and deny service to legitimate users.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on availability.

CWE-862: Missing Authorization

Reaching this weakness in Grand Restaurant WordPress <= 7.0 takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. No fixed build of this theme is recorded for Grand Restaurant WordPress yet, so installs running <= 7.0 stay exposed until the vendor ships one.

Remediation

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.

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
