CVE-2025-57807 affects the following packages: Magick.NET-Q16-x64 (NuGet), Magick.NET-Q8-x64 (NuGet), Magick.NET-Q16-HDRI-x64 (NuGet), Magick.NET-Q8-OpenMP-x64 (NuGet), Magick.NET-Q16-HDRI-OpenMP-x64 (NuGet), Magick.NET-Q16-OpenMP-x64 (NuGet), Magick.NET-Q8-arm64 (NuGet), Magick.NET-Q16-arm64 (NuGet), and 4 more. Ecosystems affected: NuGet.

How do I fix CVE-2025-57807?

Update Magick.NET-Q16-x64 to 14.8.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-57807 is resolved across your whole dependency graph.

How do I detect CVE-2025-57807 in my NuGet dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Magick.NET-Q16-x64. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2025-57807 if there is no patch (or I can't update yet)?

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.

How does O3 Security protect against CVE-2025-57807?

O3 pinpoints whether CVE-2025-57807 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2025-57807 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-57807 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-2025-57807?

CVE-2025-57807 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 19th 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-2025-57807?

CVE-2025-57807 is classified as CWE-122 (CWE-122), CWE-131 (CWE-131), Out-of-bounds Write (CWE-787). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2025-57807 published, and has it been updated?

CVE-2025-57807 was published on September 5, 2025 and was last updated on April 12, 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 is free and open-source software used for editing and manipulating digital images. ImageMagick versions lower than 14.8.2 include insecure functions: SeekBlob(), which permits advancing the stream offset beyond the current end without increasing capacity, and WriteBlob(), which then expands by quantum + length (amortized) instead of offset + length, and copies to data + offset. When offset ≫ extent, the copy targets memory beyond the allocation, producing a deterministic heap write on 64-bit builds. No 2⁶⁴ arithmetic wrap, external delegates, or policy settings are required. This is fixed in version 14.8.2.
