Content spoofing via undisclosed cross-site scripting
Published Aug 12, 2025 · Updated Feb 13, 2026
Cross-site scripting in Microsoft Dynamics 365 (on-premises) before 9.1.38.10 allows remote attackers to spoof content over a network. Microsoft has not disclosed the affected page, parameter, or input-neutralization failure that permits attacker-controlled content to reach a rendered page. Successful exploitation requires user interaction and permits content disclosure or alteration in the affected user's session without interrupting service.
