CVE-2026-93586
LowCVSS 2.9Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a use-after-free vulnerability in the ImagesToBlob method, caused by a pointer that is not updated correctly. Exploitation may result in a limited availability impact (e.g., a crash of the affected process).
Risk Assessment
An attacker can crash the image-processing process, causing a service outage. In some cases a use-after-free could potentially lead to further impact, though the described effect is limited to availability.
Recommendation
Update ImageMagick to version 7.1.2-31 or 6.9.13-56 (or later). Until patched, avoid processing untrusted images.
