    As part of its September patch Tuesday, Microsoft addressed 177 different vulnerabilities, 86 of which affect Microsoft products. None of the vulnerabilities has been exploited before today. Two of the vulnerabilities were already made public. Microsoft rates 13 of the vulnerabilities are critical.

    You will see a number of vulnerabilities without assigned severity. These vulnerabilities affect Linux distributions like Mariner, Microsoft's Linux distribution used in its cloud environments, and Azure Linux.

    Vulnerabilities of Interest:

    CVE-2025-54107, CVE-2025-54917: Microsoft assigns URLs to different security zones, like "Intranet" and "Internet". URLs may be misclassified. An attacker could use this vulnerability to bypass security features that restrict more risky URLs.

    CVE-2025-55226, CVE-2025-55236: The description for these vulnerabilities is a bit odd. Microsoft labels them as "remote code execution" vulnerabilities, but states that they allow an "authorized attacker to execute code locally." I suspect that the remote part refers to a user unknowingly executing the code by viewing an image. The CVSS score is still low for a "critical" vulnerability.

    Overall, there is no "patch now" vulnerability included. Apply patches in line with your local vulnerability management policy (hopefully before next month's patch Tuesday).
