CVE-2025-40697Network attack vector

Session compromise via unneutralized page parameter

Published Feb 19, 2026 · Updated Feb 19, 2026

Reflected XSS in Lewe WebMeasure allows remote attackers to run script in a user's browser through the page parameter in /index.php. The endpoint reflects the attacker-controlled page value into generated HTML without adequate neutralization, allowing browser interpretation as script. Exploitation is unauthenticated but requires a user to follow a crafted request; successful script runs in that user's WebMeasure origin and can read session cookies or act with the user's session.
