At a glance

CVE-2024-13887 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the Business Directory Plugin WordPress plugin, affecting versions <= 6.4.14. 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 6.4.15; sites on affected versions should update now. Disclosed March 2025, reported by Rein Daelman (trein).

Vulnerability Overview

The Business Directory Plugin – Easy Listing Directories for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.4.14 via the 'ajax_listing_submit_image_upload' function due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to add arbitrary images to listings.

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-639: Authorization Bypass Through User-Controlled Key

Business Directory Plugin <= 6.4.14 carries this weakness at ajax_listing_submit_image_upload, and reaching it takes a caller who can reach the endpoint. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Business Directory Plugin the fix is 6.4.15: builds <= 6.4.14 are affected, anything from 6.4.15 onward is not.

Remediation

Update to version 6.4.15, 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: Business Directory Plugin 6.4.15 closes this, and updating the plugin is the step that ends it.
