CVE-2022-4310Public exploitNetwork attack vector

Stored XSS via unescaped logged request URI

Published Jan 9, 2023 · Updated Apr 9, 2025

Stored XSS in VeronaLabs SlimStat Analytics before 4.9.3 allows remote attackers to run script in an administrator's browser. The request logger stores the URI without sanitization, and the Real Time access-log view renders the value without escaping. No authentication is required to plant the payload; execution requires a logged-in administrator to open the related access-log entry.
