ImageMagick allows attackers to write beyond memory limits in image files

CVE-2026-28493 GHSA-r39q-jr8h-gcq2
Summary

An attacker can create a malicious image file that exploits a weakness in the way ImageMagick handles certain types of images, potentially allowing them to execute arbitrary code or crash the application. This affects systems that use ImageMagick to process or open image files. To mitigate this risk, ensure you're running the latest version of ImageMagick and only open trusted image files from known sources.
