GHSA-r83h-crwp-3vm7

MEDIUM

GHSA-r83h-crwp-3vm7 is a medium-severity (CVSS 5.5) Use After Free vulnerability in Magick.NET-Q16-AnyCPU. O3 Security confirms whether GHSA-r83h-crwp-3vm7 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

ImageMagick has a heap-use-after-free via XMP profile could result in a crash when printing the values.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Magick.NET-Q16-AnyCPU. 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.

  2. Fix

    Update Magick.NET-Q16-AnyCPU to 14.12.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r83h-crwp-3vm7 is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-r83h-crwp-3vm7 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-r83h-crwp-3vm7. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
