At a glance

CVE-2023-27625 is a medium-severity Missing Authorization vulnerability in the Site Reviews WordPress plugin, affecting versions <= 6.5.0. It carries a CVSS score of 5.4 (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 6.6.0; sites on affected versions should update now. Disclosed March 2023, reported by Rafshanzani Suhada.

Vulnerability Overview

The Site Reviews plugin for WordPress is vulnerable to setting modification and information disclosure due to lack of capability checks in a variety of functions, including rollbackPluginAjax, downloadConsole, downloadSystemInfo and exportSettings in versions up to, and including, 6.5.1. These functions are also vulnerable to Cross-Site Request Forgery due to missing or incorrect nonce validation. This makes it possible for authenticated attackers with subscriber-level access, and above, to tamper with the console logging level amongst other actions like rolling back the plugin's version.

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 Site Reviews <= 6.5.0 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 Site Reviews the fix is 6.6.0: builds <= 6.5.0 are affected, anything from 6.6.0 onward is not.

Remediation

Update to version 6.6.0, 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: Site Reviews 6.6.0 closes this, and updating the plugin is the step that ends it.
