ImageMagick before 7.1.2-19 contains a heap buffer overflow vulnerability in the magnify operation that allows attackers to read out of bounds memory. An unrecognized magnify:method value triggers an out of bounds read, potentially exposing sensitive information or causing denial of service.
CVE-2026-56372
This critical-severity CVE scores 9.1 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 90% of all CVEs by exploit prediction. GitHub Security Advisory enrichment pending alignment with NVD CVSS.
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
