CVE-2026-5231Public exploitNetwork attack vector

Admin-session script execution via stored UTM source

Published Apr 17, 2026 · Updated Apr 17, 2026

Stored XSS in VeronaLabs WP Statistics 14.16.4 and earlier allows remote attackers to run scripts in administrators' browsers via utm_source. The referral parser stores the raw parameter as source_name after a wildcard channel-domain match, and chart.js later inserts it into legend markup through innerHTML without escaping. Execution requires an administrator to open Referrals Overview or Social Media analytics, where the script runs with that dashboard session's authority.
