Listdom: AI-powered Business Directory with Classifieds Ads Listings <= 5.8.1 - Unauthenticated Stored Cross-Site Scripting via 'lsd[displ][style]' Parameter
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.
