CVE-2026-123614
imgproxy 4.0.0 before 4.0.16 Heap Buffer Overflow via ICO Loader Integer Overflow
imgproxy from 4.0.0 before 4.0.16 contains an integer overflow in the ICO loader that allows remote attackers to trigger a heap buffer overflow via a crafted data_size value. Attackers can submit a crafted ICO image whose data_size wraps the allocation in vips/icoload.c, corrupting heap memory to crash the process or achieve code execution.
