Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a crafted image could cause an out of bounds heap write inside the WaveletDenoiseImage method. When processing a crafted image with the -wavelet-denoise operation an out of bounds write can occur. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Magick.NET-Q16-AnyCPU, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update Magick.NET-Q16-AnyCPU to 14.10.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-30936 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
This is a MODERATE impact vulnerability. ImageMagick in Red Hat Enterprise Linux 6 ELS and 7 ELS is affected by a heap buffer overflow. This flaw occurs when processing a specially crafted image using the -wavelet-denoise operation, which could lead to an out-of-bounds write. Exploitation requires user interaction to…
To reduce the risk of exploitation, avoid processing untrusted or unverified image files with ImageMagick. Users should exercise caution when handling images from unknown sources. Additionally, consider restricting ImageMagick's capabilities through its policy file to limit exposure to potentially vulnerable operations or file formats.Source: Red Hat security advisory for CVE-2026-30936 (CC BY 4.0)
