CVE-2025-68935Network attack vector

Authenticated script execution via multilevel-list Font field

Published Dec 25, 2025 · Updated Dec 25, 2025

Cross-site scripting in ONLYOFFICE Docs before 9.2.1 allows remote authenticated users to execute scripts via a crafted Font field. The Multilevel list settings window inserts attacker-controlled Font field content into the editor interface without neutralizing executable web content. A low-privileged account must supply the field; successful execution can read or alter data available to the affected editor session.
