Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, Magick fails to check for multi-layer nested mvg conversions to svg, leading to DoS. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

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 14.10.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wg3g-gvx5-2pmv is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
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 MODERATE impact denial of service vulnerability in ImageMagick affects Red Hat Enterprise Linux 6 ELS and 7 ELS, as well as Fedora and EPEL. The flaw occurs when converting multi-layer nested MVG files to SVG, where ImageMagick fails to properly validate the input, leading to resource exhaustion. Systems…
Since this vulnerability involves processing untrusted image files, it is recommended to avoid converting multi-layer nested MVG files from untrusted sources to SVG format. Implement strict input validation and sanitization for any image files processed by ImageMagick. Additionally, consider running ImageMagick in a sandboxed environment to limit potential impact.Source: Red Hat security advisory for GHSA-wg3g-gvx5-2pmv (CC BY 4.0)
