On July 14, 2026, Microsoft released a Patch Tuesday update that includes fixes for 622 vulnerabilities in Microsoft products, excluding 427 additional vulnerabilities in Chromium that affect the Microsoft Edge browser. Of these vulnerabilities, 62 are classified as critical. Before the patch release, one vulnerability was publicly disclosed and two were already exploited in active attacks. This large-scale update addresses a broad spectrum of security issues, reflecting a substantial effort to mitigate critical and actively exploited vulnerabilities.

The vulnerabilities addressed include 62 critical issues, which pose a high risk to affected systems if left unpatched. The presence of two vulnerabilities already exploited in the wild indicates active threats targeting these weaknesses. The large number of vulnerabilities, including those in Chromium impacting Microsoft Edge, increases the attack surface and potential for exploitation. Systems not updated promptly may be at significant risk of compromise.

Apply the July 2026 Microsoft Patch Tuesday updates promptly to remediate the 622 Microsoft vulnerabilities and the 427 Chromium vulnerabilities affecting Microsoft Edge.
