Severity is medium. When using an image with mask the Floyd-Steinberg dithering method will cause a negative heap buffer over-write.
AI coding agents often install or upgrade packages automatically in nuget. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
