ImageMagick before 7.1.2-15 contains a memory leak vulnerability in multiple coders that write raw pixel data where allocated objects are not properly freed. Attackers can trigger this leak by processing specially crafted images, causing memory exhaustion and denial of service.
CVE-2026-56368
This low-severity CVE scores 3.7 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- 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.
