Stored XSS via unencoded profile names
Published Jun 16, 2025 · Updated Jun 17, 2025
Stored XSS in Intermesh BV GroupOffice before 6.8.123 and 25.0.27 allows remote authenticated users to execute JavaScript in another user's browser. The profile Name field stores attacker-controlled first or last names, and the Synchronization Address books dialog renders them without HTML encoding. An attacker must save a payload in an accessible profile and have another user add that account to an address book, enabling browser-origin requests, session-data theft, or account actions.
