Microsoft and Adobe Patch Tuesday, November 2026 Security Update Review - Qualys

As the year approaches its final stretch, Microsoft's November 2026 Patch Tuesday highlights the continued importance of proactive vulnerability management. This month's security updates address vulnerabilities across the Microsoft ecosystem, reinforcing the need for organizations to promptly identify, prioritize, and remediate security risks.

In this month's updates, Microsoft addressed 1,235 vulnerabilities, including 63 critical and 1,029 important-severity vulnerabilities. The updates also addressed 142 vulnerabilities specifically impacting Microsoft Edge (Chromium-based). Notably, only one vulnerability has been exploited in the wild so far.

Remote Code Execution Risks

This month's release includes fixes for several vulnerabilities that could potentially enable remote code execution, privilege escalation, or denial-of-service attacks. An unauthenticated attacker could send a specially crafted message file and convince a user to open it in Microsoft Outlook, potentially leading to disclosure of authentication information.

Adobe Updates

Adobe has released nine advisories addressing 63 vulnerabilities across Adobe After Effects, Photoshop, Premiere, Audition, Experience Manager (AEM), and Dimension. Four of these vulnerabilities are rated critical, with successful exploitation potentially leading to arbitrary code execution.
