GHSA-869w-47c6-fq8q
Babylon Integer Overflow in Distribution Module CumulativeRewardRatio Calculation Leading to Chain Halt
Blast Radius
github.com/babylonlabs-io/babylonReal-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
Summary
Minting large amount of tokens through ibc transfer and then depositing them in validator rewards pool (via DepositValidatorRewardsPool message) can lead to integer overflow panic when calculating cumulative_reward_ratio for the validator.
This calculation happens in x/epoching module EndBlocker, thus the panic will halt the chain.
Impact
Denial of Service - Due to panic in the EndBlocker Babylon Genesis will halt
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/babylonlabs-io/babylon. 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/babylonlabs-io/babylon to 1.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-869w-47c6-fq8q 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-869w-47c6-fq8q 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-869w-47c6-fq8q. 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-869w-47c6-fq8q in your dependencies?
O3 detects GHSA-869w-47c6-fq8q across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
