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

Detection & mitigation playbook

Open-source dependency
  1. Detect

    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.

  2. 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.

  3. 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.

  4. 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

### 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
