What is CVE-2026-93587?
CVE-2026-93587 is a medium-severity denial of service vulnerability in Imagemagick Imagemagick, published on 18 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a policy bypass in the PCD (and, per the upstream advisory, CUBE and HALD) coder: when a specific command line option is supplied, the decoder does not check a configured resource limit, which can result in extra memory allocation. A local user able to pass command line options to ImageMagick can therefore exceed the intended memory policy limit, causing a limited availability impact. The issue is fixed in 7.1.2-31 and 6.9.13-56.
