CVE-2025-25191Public exploitNetwork attack vector

Administrator-session script execution via unencoded history data

Published Mar 6, 2025 · Updated Mar 6, 2025

Stored XSS in the History view of Intermesh BV GroupOffice 6.8.99 allows remote authenticated users to execute JavaScript. LogEntryGrid.js inserts stored name-derived history data and record descriptions into HTML without encoding, so a crafted name becomes executable markup. A low-privileged user must change the profile name, and execution occurs when an administrator opens the affected History entry.
