Reflected XSS via unescaped get_listings hash values

Published Sep 19, 2026 · Updated Sep 19, 2026

Reflected XSS in Estatik Real Estate Plugin 4.0.1 through 4.3.4 allows remote attackers to run script via a crafted AJAX request. The unauthenticated get_listings AJAX handler decodes several values from its hash request parameter and returns them without sanitization or output escaping. Execution requires a user to load attacker-controlled content that invokes the response, after which script runs in the affected site's browser context.
