Spoofing through an undisclosed mechanism
Published Mar 11, 2021 · Updated Aug 19, 2026
Spoofing in Microsoft SharePoint Foundation 2013, Server 2016, and Server 2019 allows attackers unspecified impact via unspecified vectors. Microsoft has not published the affected component, untrusted input, or incorrect operation that produces the spoofed result. The Microsoft assessment places the attacker locally with administrator-level privileges before the undisclosed condition is reachable.
