Microsoft July 2026 Patch Tuesday fixes massive 570 flaws, 3 zero-days

Today is Microsoft's July 2026 Patch Tuesday, and with it comes security updates for a record-breaking 570 flaws, including two zero-day vulnerabilities exploited in attacks and one publicly disclosed.

Patch Tuesday addresses 59 "Critical" vulnerabilities, 48 of which are remote code execution, 9 are elevation of privilege, 1 is a security bypass, and 1 is a spoofing.

The approximate number of bugs in each vulnerability category is listed below:

254 Elevation of Privilege Vulnerabilities

17 Security Feature Bypass Vulnerabilities

145 Remote Code Execution Vulnerabilities

102 Information Disclosure Vulnerabilities

35 Denial of Service Vulnerabilities

16 Spoofing Vulnerabilities

When BleepingComputer reports on Patch Tuesday security updates, we only count those released by Microsoft today.

Therefore, the number of flaws does not include flaws in Mariner, Azure OpenAI, Azure Synapse, M365 Copilot, Microsoft Exchange Online, Microsoft Edge for Android, and Microsoft Entra Provisioning Service that were fixed by Microsoft earlier this month.

There were also a massive 468 Microsoft Edge/Chromium flaws that were fixed by Google this month, which were excluded from this Patch Tuesday roundup. As part of last month's June Patch Tuesday, Google fixed 360 flaws that were later ported to Microsoft Edge.

Last week, Microsoft warned that there would be an increase in Patch Tuesday security updates as it has begun to use an AI-powered vulnerability discovery system to identify more security flaws across its Windows codebase before attackers can exploit them.

To learn more about the non-security updates released today, you can review our dedicated articles on the Windows 11 KB5101650 & KB5099414 cumulative updates and the Windows 10 KB5099539 extended security update.

Microsoft patches 3 zero-days

This month's Patch Tuesday fixes three zero-day vulnerabilities, with two exploited in attacks and one publicly disclosed.

Microsoft classifies a zero-day flaw as publicly disclosed or actively exploited while no official fix is available.

The two actively exploited zero-days addressed during this month's Patch Tuesday are:

CVE-2026-56155 - Active Directory Federation Services Elevation of Privilege Vulnerability

Microsoft has patched an actively exploited vulnerability in Active Directory Federation Services that grants administrative privileges.

"Insufficient granularity of access control in Active Directory Federation Services (AD FS) allows an authorized attacker to elevate privileges locally," warns Microsoft.

Microsoft credited the flaw to Jeremy Kingston and Scott Clark of Microsoft Detection and Response Team (DART), Microsoft's incident response unit, indicating it was likely uncovered while investigating active attacks.

Microsoft has not disclosed any details as to how the flaw was exploited in attacks.

CVE-2026-56164 - Microsoft SharePoint Server Elevation of Privilege Vulnerability

Microsoft has patched an actively exploited flaw in Microsoft SharePoint Server that allows a remote attacker to gain elevated privileges.

"Missing authentication for critical function in Microsoft Office SharePoint allows an unauthorized attacker to elevate privileges over a network," explains Microsoft.

Microsoft says that enabling the Antimalware Scan Interface (AMSI) on the server and setting the Request Body Scan mode to Full can help mitigate this flaw.

No details have been released as to how this flaw was exploited in attacks.

Microsoft credited the flaw to Jayson Frost with Mandiant Incident Response, Genwei Jiang with Google Cloud, FLARE OTF, and an anonymous researcher.

The publicly disclosed zero-day that was fixed is:

CVE-2026-50661 - Windows BitLocker Security Feature Bypass Vulnerability

Microsoft has patched a publicly disclosed Windows BitLocker bypass flaw that could allow attackers to gain access to encrypted data.

"A successful attacker could bypass the BitLocker Device Encryption feature on the system storage device. An attacker with physical access to the target could exploit this vulnerability to gain access to encrypted data," explains Microsoft.

Microsoft attributed the flaw to an anonymous researcher.

Recent updates from other companies
