Publication date: 2026-09-01

Last updated on: 2026-09-01

Assigner: Wordfence

Description
The Listdom: AI-powered Business Directory with Classifieds Ads Listings plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'lsd[displ][style]' Parameter in all versions up to, and including, 5.8.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the Listdom Pro add-on to be active and the 'Display Options Per Listing' displ setting to be enabled, both of which are non-default configurations.

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the Listdom WordPress plugin. It allows unauthenticated attackers to inject malicious scripts into web pages by exploiting insufficient input sanitization and output escaping in the 'lsd[displ][style]' parameter. The attack requires specific non-default settings: the Listdom Pro add-on must be active and the 'Display Options Per Listing' displ setting must be enabled.

The injected scripts execute when users access the compromised pages, potentially stealing data or performing unauthorized actions on behalf of users.

Detection Guidance

Check if the Listdom plugin is installed and active in WordPress. Verify if the Listdom Pro add-on is enabled and the 'Display Options Per Listing' displ setting is turned on. Inspect WordPress pages for unusual scripts or payloads in the 'lsd[displ][style]' parameter.

Impact Analysis

If you use the Listdom plugin with the required non-default settings, attackers could steal your cookies, session tokens, or other sensitive data. They might also perform actions as you on the website, such as changing settings or posting unauthorized content.

Visitors to your site could have their browsers hijacked, leading to malware infections or phishing attacks. The impact depends on the privileges of the affected user accounts.

Compliance Impact

This vulnerability could lead to data breaches, violating GDPR's data protection requirements if personal data is exposed. For HIPAA, it may compromise protected health information if such data is processed on the site.

Organizations may face fines or penalties for non-compliance if the vulnerability results in unauthorized access to sensitive data. Immediate patching and remediation are recommended to maintain compliance.

Mitigation Strategies

Update the Listdom plugin to the latest version (5.8.2 or higher). Disable the Listdom Pro add-on if not needed. Disable the 'Display Options Per Listing' displ setting if enabled. Monitor WordPress pages for signs of exploitation.
