GHSA-m6gx-rhvj-fh52
GHSA-m6gx-rhvj-fh52 is a security vulnerability in github.com/ethereum/go-ethereum. O3 Security confirms whether GHSA-m6gx-rhvj-fh52 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Denial of service in go-ethereum due to CVE-2020-28362
Real-World Exposure
github.com/ethereum/go-ethereumReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Versions of Geth built with Go <1.15.5 or <1.14.12 are most likely affected by a critical DoS-related security vulnerability. The golang team has registered the underlying flaw as ‘CVE-2020-28362’.
We recommend all users to rebuild (ideally v1.9.24) with Go 1.15.5 or 1.14.12, to avoid node crashes. Alternatively, if you are running binaries distributed via one of our official channels, we’re going to release v1.9.24 ourselves built with Go 1.15.5.
Patches
This is not an issue in go-ethereum, rebuilding an older version with Go 1.15.5 or 1.14.12 will suffice to address the vulnerability.
Workarounds
Rebuilding with Go 1.15.5 or 1.14.12 will suffice to address the vulnerability.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/ethereum/go-ethereum. 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 github.com/ethereum/go-ethereum to 1.9.24 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m6gx-rhvj-fh52 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-m6gx-rhvj-fh52 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-m6gx-rhvj-fh52. 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-m6gx-rhvj-fh52 in your dependencies?
O3 detects GHSA-m6gx-rhvj-fh52 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
