Cosmos EVM Vulnerability
Blast Radius
github.com/cosmos/evm🐹github.com/cosmos/evmReal-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
Patches
Patched in versions v0.3.1, v0.4.2, and in the v0.5.0 release. More information will be disclosed at a later point to ensure chains have time to safely upgrade.
Workarounds
No workarounds for chains that make use of static or dynamic precompiles. Upgrading is strongly recommended.
Testing
Tests are introduced in every affected version.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/cosmos/evm. 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/cosmos/evm to 0.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8pfh-j44r-f654 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-8pfh-j44r-f654 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-8pfh-j44r-f654. 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-8pfh-j44r-f654 in your dependencies?
O3 detects GHSA-8pfh-j44r-f654 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
