Which packages are affected by CVE-2026-56379?

CVE-2026-56379 affects the following packages: Magick.NET-Q16-AnyCPU (NuGet), Magick.NET-Q16-HDRI-AnyCPU (NuGet), Magick.NET-Q16-HDRI-OpenMP-arm64 (NuGet), Magick.NET-Q16-HDRI-OpenMP-x64 (NuGet), Magick.NET-Q16-HDRI-arm64 (NuGet), Magick.NET-Q16-HDRI-x64 (NuGet), Magick.NET-Q16-HDRI-x86 (NuGet), Magick.NET-Q16-OpenMP-arm64 (NuGet), and 11 more. Ecosystems affected: NuGet.

How do I fix CVE-2026-56379?

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 CVE-2026-56379 is resolved across your whole dependency graph.

How do I detect CVE-2026-56379 in my NuGet dependencies?

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.

How do I mitigate CVE-2026-56379 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2026-56379 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-56379 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-56379?

CVE-2026-56379 has an EPSS (Exploit Prediction Scoring System) score of 1.6%, placing it in the 77th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-56379?

CVE-2026-56379 is classified as CWE-116 (CWE-116), OS Command Injection (CWE-78). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2026-56379 published, and has it been updated?

CVE-2026-56379 was published on June 23, 2026 and was last updated on October 31, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

ImageMagick before 7.1.2-15 and 6.9.13-40 contains a command injection vulnerability in the SVG decoder that allows attackers to inject arbitrary MVG drawing commands. Attackers can craft malicious SVG files with injected Magick Vector Graphics commands that execute during rendering.

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.

Red HatImportant

An Important-rated vulnerability in the default configuration of Mojolicious::Plugin::Web::Auth::OAuth2 allows remote attackers to hijack user sessions. Because the plugin defaults to generating predictable security tokens, an attacker can bypass protections and launch Cross-Site Request Forgery (CSRF) attacks against…

Workaround published by Red Hat

Restrict ImageMagick processing capabilities via policy.xml, disabling the SVG coder and restricting delegates to prevent injection escalation to OS command execution. Enforce mandatory access control (SELinux/AppArmor) combined with seccomp syscall filtering to block execve. For systemd services, enable NoNewPrivileges, ProtectSystem=strict, ProtectHome=true, and PrivateDevices=true.
