GHSA-mv8x-668m-53fg
CRITICALGHSA-mv8x-668m-53fg is a critical-severity (CVSS 9.8) CWE-665 vulnerability in github.com/ElrondNetwork/elrond-go. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-mv8x-668m-53fg is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-World Exposure
github.com/ElrondNetwork/elrond-goReal-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
Read only calls between contracts can generate smart contracts results. For example, if contract A calls in read only mode contract B and the called function will make changes upon the contract's B state, the state will be altered for contract B as if the call was not made in the read-only mode. This can lead to some effects not designed by the original smart contracts programmers.
Patches
Patch v1.3.35 or higher
Workarounds
No workaround
References
For future reference and understanding of this issue, anyone can check this integration test https://github.com/ElrondNetwork/elrond-go/blob/8e402fa6d7e91e779980122d3798b2bf50892945/integrationTests/vm/txsFee/asyncESDT_test.go#L452 that proves the fix and prevents a future code regression.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/ElrondNetwork/elrond-go. 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/ElrondNetwork/elrond-go to 1.3.35 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mv8x-668m-53fg 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-mv8x-668m-53fg 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-mv8x-668m-53fg. 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-mv8x-668m-53fg in your dependencies?
O3 detects GHSA-mv8x-668m-53fg across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
