At a glance

CVE-2023-47513 is a medium-severity Improper Authorization vulnerability in the ARI Stream Quiz WordPress plugin, affecting versions <= 1.3.2. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 1.3.3; sites on affected versions should update now. Disclosed November 2023, reported by Abdi Pranata.

Vulnerability Overview

The ARI Stream Quiz – WordPress Quizzes Builder plugin for WordPress is vulnerable to content injection due to improper capability checks on the quiz editing functionality in all versions up to, and including, 1.3.2. This makes it possible for authenticated attackers, with contributor access and above, to publish quizzes containing arbitrary content on the site without review.

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 ARI Stream Quiz <= 1.3.2 takes an account at Contributor level or above. 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 ARI Stream Quiz the fix is 1.3.3: builds <= 1.3.2 are affected, anything from 1.3.3 onward is not.

Remediation

Update to version 1.3.3, 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: ARI Stream Quiz 1.3.3 closes this, and updating the plugin is the step that ends it.
