Authenticated security bypass via SharePoint request
Published Feb 9, 2022 · Updated Jan 2, 2025
Security feature bypass in Microsoft SharePoint Server 2016 16.0.0 through 16.0.5278.1000 allows remote authenticated users to bypass security controls via network requests. Microsoft has not publicly disclosed the specific SharePoint component or operation that mishandles untrusted input, so the mechanism remains unspecified. Exploitation requires a valid low-privilege SharePoint account; published impact is limited to security-control bypass and associated confidentiality exposure, with no documented integrity or availability impact.
