Answer in brief
CVE-2026-56362 records a Low severity (CVSS 3.3) vulnerability in ImageMagick - Heap-buffer-overflow Read in GetPixelIndex via OpenPixelCache Metadata Desynchronization. The current sources do not mark it as known exploited. The current feed maps ImageMagick/ImageMagick (generic), ImageMagick/ImageMagick (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 3.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

ImageMagick before 7.1.2-15 contains a heap-buffer-overflow read vulnerability in GetPixelIndex caused by OpenPixelCache updating image channel metadata before pixel cache memory allocation. Attackers can trigger memory and disk allocation failures to cause a heap-buffer-overflow read affecting any writer calling GetPixelIndex.
