This CVE is among the lower half of tracked Microsoft CVEs by EPSS exploit probability.
CVE-2025-53799 is an information disclosure flaw in the Windows Imaging Component, the image-parsing library that decodes formats like JPEG and TIFF, on Windows 10 Version 1809 and Windows Server 2019. The High Severity rating with CVSS 8.8 is unusually elevated for a disclosure issue, which suggests exploitation can leak sensitive memory contents when a crafted image is opened. It is not in CISA KEV and has no known ransomware use, but the 19 percent EPSS score is notable for an unexploited bug and reflects the low bar of tricking a user into viewing an image.
Do this: Deploy the Microsoft patch for CVE-2025-53799 to all Windows 10 1809 and Server 2019 systems, prioritizing endpoints where users open images from email or the web.
