At a glance

CVE-2025-66063 is a medium-severity Missing Authorization vulnerability in the WP Google Review Slider WordPress plugin, affecting versions <= 17.4. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 17.6; sites on affected versions should update now. Disclosed November 2025, reported by Nabil Irawan.

Vulnerability Overview

The WP Google Review Slider plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 17.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to perform an unauthorized action.

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 interaction from a victim user.

CWE-862: Missing Authorization

Reaching this weakness in WP Google Review Slider <= 17.4 takes a caller who can reach the endpoint. 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. For WP Google Review Slider the fix is 17.6: builds <= 17.4 are affected, anything from 17.6 onward is not.

Remediation

Update to version 17.6, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: WP Google Review Slider 17.6 closes this, and updating the plugin is the step that ends it.
