CVE-2024-9548Network attack vector

Stored XSS via unescaped visitor resource

Published Oct 14, 2024 · Updated Apr 8, 2026

Stored XSS in VeronaLabs SlimStat Analytics 5.2.6 and earlier allows remote attackers to execute scripts via a crafted resource value. The visitor-request logger stores the resource parameter without sufficient sanitization, and the right-now analytics view renders it without output escaping. No authentication is required to plant a payload; execution occurs when a user opens the affected analytics page, exposing that user's WordPress session context.
