What is CVE-2026-93590?

ImageMagick versions prior to 7.1.2-31 possess a vulnerability in the UHDR encoder that fails to properly enforce resource policies during buffer allocation for image pixels.

It is crucial for users of ImageMagick to review and mitigate this vulnerability to ensure their systems remain secure.
