Description
CVE-2025-71330 is a denial of service vulnerability in the image-size library up to version 2.0.2. It allows remote attackers to cause an infinite loop in the ICNS image parser by supplying a specially crafted ICNS buffer with a zero-valued entry length field. This infinite loop blocks the Node.js event loop permanently, causing a denial of service.
