At a glance

CVE-2024-0881 is a medium-severity Improper Access Control vulnerability in the Post Grid WordPress plugin, affecting versions <= 2.2.74. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.2.76; sites on affected versions should update now. Disclosed March 2024, reported by Krzysztof Zając.

Vulnerability Overview

The Post Grid, Form Maker, Popup Maker, WooCommerce Blocks, Post Blocks, Post Carousel plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.2.74 via the post_grid_paginate_ajax_free AJAX endpoint. This makes it possible for unauthenticated attackers to retrieve private and password protected posts that may contain sensitive information.

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 Post Grid <= 2.2.74 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 Post Grid the fix is 2.2.76: builds <= 2.2.74 are affected, anything from 2.2.76 onward is not.

Remediation

Update to version 2.2.76, 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: Post Grid 2.2.76 closes this, and updating the plugin is the step that ends it.
