Authenticated script execution via undisclosed web input
Published Feb 13, 2024 · Updated Aug 10, 2026
Cross-site scripting in Microsoft Dynamics 365 Customer Engagement before 9.1.25.17 allows remote authenticated users to run script. Microsoft has not disclosed the affected page, parameter, or server-side operation that fails to neutralize attacker-controlled input before web-page generation. Exploitation requires low-privileged access and victim interaction with attacker-controlled content, after which script executes in the victim browser context.
