CVE-2026-19796Network attack vector

Unauthenticated stored XSS via unescaped listing style

Published Sep 1, 2026 · Updated Sep 1, 2026

Stored XSS in Webilia Listdom 5.8.1 and earlier allows remote attackers to execute arbitrary scripts in visitors' browsers. Listing-processing code stores the lsd[displ][style] parameter without sufficient sanitization and renders it without adequate output escaping. The non-default Listdom Pro add-on and Display Options Per Listing setting must both be active, after which injected scripts run when visitors access the affected page.
