This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
Component: wasmvm Criticality: Medium (ACMv1: I:Moderate; L:Likely) Patched versions: wasmvm 1.5.4, 2.0.3, 2.1.2
Some Wasm operations take significantly more gas than our benchmarks indicated. This can lead to missing the gas target we defined by a factor of ~10x. This means a malicious contract could take 10 times as much time to execute as expected, which can be used to temporarily DoS a chain.
See CWA-2024-004 for more details.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cosmwasm-vm. 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 cosmwasm-vm to 1.5.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rg2q-2jh9-447q 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-rg2q-2jh9-447q 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-rg2q-2jh9-447q. 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-rg2q-2jh9-447q in your dependencies?
O3 detects GHSA-rg2q-2jh9-447q across crates.io, Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
