Authenticated script execution via comment editing textarea
Published Dec 24, 2025 · Updated Dec 24, 2025
Cross-site scripting in ONLYOFFICE Docs before 9.2.1 allows remote authenticated users to execute script through the comment editing form. The vulnerable locus is the form's textarea; public vendor material does not disclose the exact missing encoding or sanitization operation. A low-privileged account is required, and successful injection can read or alter data exposed to the affected browser context without interrupting service.
