Description
Description
Microsoft is releasing this security advisory to provide information about a vulnerability in .NET 6.0 and .NET Core 3.1, NuGet (NuGet.exe, NuGet.Commands, NuGet.CommandLine, NuGet.CommandLine.XPlat version range from 3.5.0 to 6.2.0). This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.
A vulnerability exists in .NET 6.0, .NET Core 3.1, and NuGet (NuGet.exe, NuGet.Commands, NuGet.CommandLine, NuGet.CommandLine.XPlat version range from 3.5.0 to 6.2.0) where a nuget.org api key could leak due to an incorrect comparison with a server url.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for NuGet.Commands. 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.
Fix
Update NuGet.Commands to 4.9.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3885-8gqc-3wpf 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.
How O3 protects you
O3 pinpoints whether GHSA-3885-8gqc-3wpf 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-3885-8gqc-3wpf. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-3885-8gqc-3wpf in your dependencies?
O3 detects GHSA-3885-8gqc-3wpf across NuGet dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
