Authenticated script execution via unsanitized request reflection
Published Mar 12, 2020 · Updated Feb 28, 2025
Reflected XSS in affected Microsoft SharePoint servers allows remote authenticated users to execute script via a crafted request. SharePoint fails to sanitize attacker-controlled request content before reflecting it into a response, but Microsoft has not named the endpoint or parameter. Exploitation requires SharePoint credentials and user interaction; successful script runs in the affected user's browser context.
