At a glance

CVE-2019-25060 is a medium-severity Improper Access Control vulnerability in the WPGraphQL WordPress plugin, affecting versions <= 0.3.4. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 0.3.5; sites on affected versions should update now. Disclosed July 2019, reported by Rohan Pagey.

Vulnerability Overview

The WPGraphQL WordPress plugin before 0.3.5 doesn't properly restrict access to information about other users' roles on the affected site. Because of this, a remote attacker could forge a GraphQL query to retrieve the account roles of every user on the site.

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-284: Improper Access Control

Reaching this weakness in WPGraphQL <= 0.3.4 takes a caller who can reach the endpoint. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.

Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For WPGraphQL the fix is 0.3.5: builds <= 0.3.4 are affected, anything from 0.3.5 onward is not.

Remediation

Update to version 0.3.5, 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: WPGraphQL 0.3.5 closes this, and updating the plugin is the step that ends it.
