CVE-2026-61857Network attack vector

Application crash via unchecked XMP entity resize

Published Jul 11, 2026 · Updated Jul 11, 2026

Heap use-after-free in ImageMagick 7 before 7.1.2-26 and 6 before 6.9.13-51 allows remote attackers to crash applications. ParseEntities in MagickCore/xml-tree.c fails to check whether ResizeQuantumMemory returns null while expanding entities in a crafted XMP profile, then writes through the invalid pointer. Exploitation requires XMP metadata to reach the shared XML parser; the documented consequence is an application crash, not data access or code execution.
