Authenticated script execution via unsanitized web request
Published Apr 15, 2020 · Updated Feb 28, 2025
Cross-site scripting in Microsoft SharePoint products allows remote authenticated users to execute script via a crafted web request. Microsoft identifies improper sanitization of the request but has not disclosed the affected endpoint, parameter, or encoding path. Exploitation requires low-privileged access and victim interaction; successful script execution can read or alter data in the victim’s SharePoint security context.
