Vulnerability Overview

WordPress before 3.7.2 and 3.8.x before 3.8.2 allows remote authenticated users to publish posts by leveraging the Contributor role, related to wp-admin/includes/post.php and wp-admin/includes/class-wp-posts-list-table.php.

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-285: Improper Authorization

Reaching this weakness in WordPress 3.8 3.7 – 3.8.1 · 3 branches takes a caller who can reach the endpoint. Improper authorization means a permission check exists but does not cover the case being exercised, so a caller who is allowed to do one thing is allowed to do a neighbouring thing as well.

A lower-privileged account performs an action reserved for a higher one, which on a multi-author or membership site means an ordinary user reaching administrative behaviour. For WordPress 3.8 the fix is 3.7.2: builds 3.7 – 3.8.1 · 3 branches are affected, anything from 3.7.2 onward is not.

Remediation

Update to one of the following versions, or a newer patched version: 3.7.2, 3.8.2

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: updating to 3.7.2 is the step that ends it.
