CVE-2026-93588 is a low-severity vulnerability in Imagemagick Imagemagick, published on 18 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a NULL pointer dereference in the PNM coder. When the coder reaches a memory (resource) limit at a specific point during processing, the failed allocation is not handled and a NULL pointer is dereferenced, which can lead to a denial of service (application crash) when processing a specially crafted or sufficiently large PNM image.

Weakness: CWE-476 (NULL Pointer Dereference)
