Received Received - Intake

Stored XSS in CM Business Directory WordPress Plugin

Publication date: 2026-07-03

Last updated on: 2026-07-03

Assigner: Wordfence

Description
The CM Business Directory – Optimise and showcase local business plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Business Address Meta Fields in all versions up to, and including, 1.5.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Because the malicious payload is stored in post meta rather than post_content, WordPress's unfiltered_html capability restriction does not apply, meaning contributors who lack that capability can still inject executable HTML via the address meta fields such as cmbd_address, cmbd_cityTown, cmbd_stateCounty, cmbd_postalcode, cmbd_region, and cmbd_country.

Executive Summary

The CM Business Directory – Optimise and showcase local business plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in all versions up to and including 1.5.7. This vulnerability arises because the plugin does not properly sanitize input or escape output in the Business Address Meta Fields.

Authenticated users with contributor-level access or higher can inject malicious scripts into address-related meta fields such as cmbd_address, cmbd_cityTown, cmbd_stateCounty, cmbd_postalcode, cmbd_region, and cmbd_country. These scripts are stored and executed whenever a user views the affected page.

Notably, because the malicious code is stored in post meta rather than post content, WordPress's usual unfiltered_html capability restrictions do not prevent contributors from injecting executable HTML, increasing the risk.

Impact Analysis

This vulnerability can allow attackers with contributor-level access to inject malicious scripts that execute in the browsers of users who visit the affected pages.

The impact includes potential theft of user credentials, session hijacking, defacement of the website, or redirection to malicious sites.

Since the vulnerability has a CVSS base score of 6.4 with low attack complexity and no user interaction required, it poses a moderate risk to website security and user data integrity.
