At a glance
CVE-2018-11580 is a high-severity Missing Authorization vulnerability in the Mass Pages/Posts Creator WordPress plugin, affecting versions <= 1.2.2.

The issue is fixed in version 1.2.3; sites on affected versions should update now. Disclosed June 2018, reported by Jack K..
Vulnerability Overview
An issue was discovered in mass-pages-posts-creator.php in the MULTIDOTS Mass Pages/Posts Creator plugin 1.2.2 for WordPress. Any logged in user can launch Mass Pages/Posts creation with custom content. There is no nonce or user capability check, so anyone can launch a DoS attack against a site and create hundreds of thousands of posts with custom content.
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-862: Missing Authorization
Reaching this weakness in Mass Pages/Posts Creator <= 1.2.2 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 Mass Pages/Posts Creator the fix is 1.2.3: builds <= 1.2.2 are affected, anything from 1.2.3 onward is not.
Remediation
Update to version 1.2.3, 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: Mass Pages/Posts Creator 1.2.3 closes this, and updating the plugin is the step that ends it.
