Microsoft May 2026 Patch Tuesday, (Tue, May 12th)

Impact

Successful exploitation of these vulnerabilities could allow attackers to execute remote code, elevate privileges, spoof identities, cause denial of service, or disclose sensitive information on affected Microsoft products and services. The critical vulnerabilities in Netlogon and Microsoft SSO Plugin for Jira & Confluence are particularly significant due to their potential impact on authentication and supply chain security. However, no exploits are known to be active in the wild at this time, reducing immediate risk. Azure-related vulnerabilities marked as no customer action required indicate that Microsoft manages remediation for those cloud services.
