At a glance

CVE-2026-5371 is a high-severity Missing Authorization vulnerability in the MonsterInsights WordPress plugin, affecting versions <= 10.1.2. It carries a CVSS score of 7.1 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 10.1.3; sites on affected versions should update now. Disclosed May 2026, reported by Dmitrii Ignatyev.

Vulnerability Overview

The MonsterInsights – Google Analytics Dashboard for WordPress (Website Stats Made Easy) plugin for WordPress is vulnerable to unauthorized access and modification of data due to a missing capability checks on the get_ads_access_token() and reset_experience() functions in all versions up to, and including, 10.1.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve live Google OAuth access tokens and reset Plugins's Google Ads integration.

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. A successful exploit has high impact on confidentiality.

CWE-862: Missing Authorization

MonsterInsights <= 10.1.2 carries this weakness at get_ads_access_token(), and reaching it takes an account at Subscriber level or above. 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 MonsterInsights the fix is 10.1.3: builds <= 10.1.2 are affected, anything from 10.1.3 onward is not.

Remediation

Update to version 10.1.3, 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: MonsterInsights 10.1.3 closes this, and updating the plugin is the step that ends it.
