Persistent script execution via unsanitized upsell content
Published Jan 8, 2024 · Updated Apr 17, 2025
Stored XSS in the portal upsell widget in Open-Xchange OX App Suite 7.10.6-rev33 allows remote authenticated users to run script. The widget stores user-controlled content and renders it without sanitization, allowing arbitrary script to persist under the trusted application domain. An attacker needs temporary access to an account or must lure another user to a compromised account; execution can expose or alter data available to that user's session.
