    "summary": "ImageMagick before 7.1.2-33 contains a policy bypass vulnerability in the UHDR decoder that allows attackers to evade image width and height limits because extent checks occur after decoding. Attackers can supply crafted UHDR images with oversized dimensions that are fully decoded before policy limits are enforced, causing excessive resource consumption.",
