CVE-2026-11366
At a glance
CVE-2026-11366 is a medium-severity Improper Authentication vulnerability in the MonsterInsights WordPress plugin, affecting versions <= 11.0.0. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 11.1.0; sites on affected versions should update now. Disclosed July 2026, reported by Đặng Tiến Dũng.
Vulnerability Overview
The MonsterInsights – Google Analytics Dashboard for WordPress (Website Stats Made Easy) plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 11.0.0. This makes it possible for unauthenticated attackers to forge analytics data.
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.
CWE-287: Improper Authentication
Reaching this weakness in MonsterInsights <= 11.0.0 takes a caller who can reach the endpoint. Improper authentication means the mechanism that proves who a caller is can be satisfied without the secret it was supposed to require.
An attacker authenticates as another user — administrators included — without ever knowing a password, so password policies and login rate limits never come into play. For MonsterInsights the fix is 11.1.0: builds <= 11.0.0 are affected, anything from 11.1.0 onward is not.
Remediation
Update to version 11.1.0, 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: MonsterInsights 11.1.0 closes this, and updating the plugin is the step that ends it.
