CVE-2026-86420: ImageMagick before 7.1.2-30 Denial of Service Memory Budget

MediumCVSS 6.3 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 25/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.32% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
Fixed version: ImageMagick ImageMagick 6.9.13-55, 7.1.2-30.

Low priority for now. Upgrade to ImageMagick ImageMagick 6.9.13-55, 7.1.2-30 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.

Root cause

Code that parses nested structures sets no depth or size limit. A small input can turn into a disproportionate processing load.
