CVE-2026-46522
HIGHImageMagick - Infinite Loop in the MIFF decoder can lead to CPU exhaustion
Exploitation Summary
EIP tracks 1 public exploit for CVE-2026-46522. PoCs published by Jose Rivas.
AI-analyzed exploit summary This exploit demonstrates a CPU exhaustion vulnerability in ImageMagick's MIFF decoder by crafting a malformed BZip2-compressed MIFF file with a zero-length block, triggering an infinite loop in the decompressor. The PoC generates a minimal 224-byte file that causes 100% CPU usage until terminated.
Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2.23 and 6.9.13-48, due to a missing check in the MIFF decoder, a crafted file could cause an infinite loop resulting in CPU exhaustion. Versions 7.1.2.23 and 6.9.13-48 fix the issue.
