spoofing xss

The spoofing xss tag on WindowsForum.com covers discussions about cross-site scripting vulnerabilities that also enable spoofing attacks, particularly in Microsoft products. A key example is CVE-2026-26105, a high-severity spoofing XSS flaw in on-premises Microsoft SharePoint Server patched in March 2026. This vulnerability allowed unauthenticated remote attackers to inject malicious scripts that spoof trusted site content, leading to phishing, credential theft, or session hijacking. The tag focuses on security updates, CVSS scores, and remediation steps for such combined spoofing and XSS threats in enterprise environments.
