GHSA-gpv5-rp6w-58r8 is a remote code execution vulnerability in Akka. A fix is available for Akka — see the affected versions and patch details below.
Remote code execution vulnerability in dependency System.Drawing.Common
Real-World Exposure
Akka.NETAkkaReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects NuGet packages — download data is not available via public APIs for these ecosystems.
Description
Impact
The core Akka module depended on an old System.Configuration.ConfigurationManager version 4.7.0 which transitively depends on System.Common.Drawing v4.7.0. The System.Common.Drawing v4.7.0 is affected by a remote code execution vulnerability https://github.com/advisories/GHSA-ghhp-997w-qr28.
The real-world impact of this should be low, but users should be advised to upgrade to later versions of Akka.NET.
Patches
Has the problem been patched? What versions should users upgrade to?
This issue is resolved in Akka.NET v1.4.46 and Akka.NET v1.5.0-alpha3.
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?
You might be able to explicitly reference System.Configuration.ConfigurationManager's NuGet package and upgrade to 6.0.1 or later without upgrading Akka.NET, but it's probably best to upgrade Akka.NET itself.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Akka, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update Akka to 1.4.46 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gpv5-rp6w-58r8 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-gpv5-rp6w-58r8 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-gpv5-rp6w-58r8. 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-gpv5-rp6w-58r8 in your dependencies?
O3 Security finds GHSA-gpv5-rp6w-58r8 across NuGet dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
