CVE-2024-21523Public exploitNetwork attack vector

Process crash via unchecked N-API conversions

Published Jul 10, 2024 · Updated Jul 9, 2026

Denial of service in zhangyuanwei images 3.2.4 and earlier allows remote attackers to crash a Node.js process via crafted arguments. The native Image.cc bindings pass constructor, width, height, resize, rotate, and fill arguments to N-API conversion functions without validating their JavaScript types, then assert that conversion succeeded; size(0) separately triggers a segmentation fault. The host application must pass attacker-controlled values into an affected library call, and the bounded consequence is termination of that process.
