Denial of service in Microsoft Active Directory Federation Services (AD FS) allows a remote, unauthenticated attacker to crash the service by triggering a stack-based buffer overflow over the network (CVSS 7.5, availability-only impact). Because AD FS brokers single sign-on and federated authentication, a successful attack can knock out login for every downstream application that relies on it. No public exploit has been identified at time of analysis, and it is not listed in CISA KEV.
Denial of service in Microsoft Active Directory Federation Services (AD FS) lets a remote, unauthenticated attacker crash the service by triggering a stack-based buffer overflow (CWE-121) over the network. The flaw affects AD FS as shipped across a broad range of Windows client and server builds (Windows 10/11 and Windows Server 2012 through 2025). Microsoft - the reporting party - has released a patch; there is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.
Local privilege escalation in the Microsoft Windows App Store component (Windows 10 1607 through Windows 11 26H1, and Windows Server 2016 through 2025) allows an authorized low-privileged attacker to win a race condition on an improperly synchronized shared resource and gain higher privileges. Exploitation is local-only and high-complexity because it depends on reliably hitting a narrow timing window, and no public exploit has been identified at time of analysis. A vendor patch is available via Microsoft's MSRC update guide.
Remote code execution in the Microsoft Windows FTP Service allows an unauthenticated network attacker to run arbitrary code by triggering a heap-based buffer overflow (CWE-122). The flaw affects the FTP service across a broad range of Windows 10, Windows 11, and Windows Server (2019/2022/2025) builds and carries a critical CVSS 9.8 rating with no authentication or user interaction required. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the unauthenticated, network-reachable nature of the bug makes it a high-priority patch target.
Local privilege escalation in Microsoft Windows WalletService allows an authenticated low-privileged attacker to gain SYSTEM-level rights on the host, per CVSS:3.1 AV:L/AC:L/PR:L (7.8, High). The flaw stems from improper privilege management (CWE-269) in the WalletService component and affects a broad range of Windows client and server builds.
