Spoofing via unauthenticated XSS
Published Aug 6, 2026 · Updated Aug 25, 2026
Cross-site scripting in Microsoft SharePoint Online allows remote attackers to perform spoofing via crafted web content. Microsoft has not publicly identified the affected page or parameter, but the published record describes improper neutralization during page generation, meaning attacker-controlled input is rendered into HTML without safe output encoding. The attack is network-reachable and user interaction is required; the public record bounds the consequence to spoofing and does not disclose a direct data read, write, or service interruption path.
