At a glance

CVE-2021-24733 is a medium-severity Incorrect Authorization vulnerability in the WP Post Page Clone WordPress plugin, affecting versions <= 1.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 1.2; sites on affected versions should update now. Disclosed December 2021, reported by apple502j.

Vulnerability Overview

The WP Post Page Clone WordPress plugin before 1.2 allows users with a role as low as Contributor to clone and view other users' draft and password-protected posts which they cannot view normally.

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-863: Incorrect Authorization

Reaching this weakness in WP Post Page Clone <= 1.1 takes a caller who can reach the endpoint. Incorrect authorization means a permission check exists but evaluates the wrong thing, so it passes for callers it was meant to stop.

The action runs for users the code intended to exclude, with the same effect as having no check at all. For WP Post Page Clone the fix is 1.2: builds <= 1.1 are affected, anything from 1.2 onward is not.

Remediation

Update to version 1.2, 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: WP Post Page Clone 1.2 closes this, and updating the plugin is the step that ends it.
