CWE-269: Improper Privilege Management

Reaching this weakness in Maps Plugin using Google Maps for WordPress <= 1.8.0 takes a caller who can reach the endpoint. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Maps Plugin using Google Maps for WordPress the fix is 1.8.1: builds <= 1.8.0 are affected, anything from 1.8.1 onward is not.

Remediation

Update to version 1.8.1, 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: Maps Plugin using Google Maps for WordPress 1.8.1 closes this, and updating the plugin is the step that ends it.
