Privilege escalation via server-side request forgery
Published Aug 11, 2026 · Updated Aug 25, 2026
Server-side request forgery in Microsoft SharePoint before August 2026 updates lets remote authenticated users elevate privileges over a network. Microsoft has not disclosed which SharePoint component dereferences attacker-controlled destinations or how the SSRF condition crosses privilege boundaries; the public record names only an SSRF flaw in SharePoint. Authenticated access to a vulnerable SharePoint server is required, and the published advisories do not describe any consequence beyond gaining higher privileges within the environment.
