ImageMagick before 7.1.2-30 and 6.9.13-55 fails to properly lower the memory budget when an operation inside OpenPixelCache fails. Repeated triggering of such failures can exhaust the process memory budget and result in a denial of service.
CVE-2026-86420
This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 63% 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.
