CVE-2025-14151Network attack vector

Unauthenticated stored XSS via outbound_resource tracking input

Published Dec 19, 2025 · Updated Dec 19, 2025

Stored XSS in VeronaLabs SlimStat Analytics 5.3.2 and earlier allows remote attackers to inject scripts via outbound_resource. The slimtrack AJAX action accepts outbound_resource without sufficient sanitization, and analytics report views render the stored value without adequate output escaping. No authentication is required, and the payload executes under the site's origin when an affected report is viewed, exposing browser-accessible data and actions in that user's session.
