CVE-2023-24920Network attack vector

Authenticated browser script execution via undisclosed input

Published Mar 14, 2023 · Updated Feb 28, 2025

Cross-site scripting in Dynamics 365 (on-premises) before 9.0.45.11 or 9.1.16.20 allows remote authenticated users to execute script. Microsoft has not published the affected request, input field, or encoding failure, so the precise script-injection locus remains undisclosed. Exploitation requires an authenticated user and another user's interaction, and it can expose or alter data in that user's browser session.
