Description

Summary

Sending transactions with fees different than native Babylon genesis denom (ubbn) leads to chain halt.

Impact

Denial of Service - Due to panic in the x/distribution module BeginBlocker triggered by a error when sending fees from feeCollector to x/distribution module - https://github.com/cosmos/cosmos-sdk/blob/main/x/distribution/keeper/allocation.go#L28 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/v2, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/babylonlabs-io/babylon/v2 to 2.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-56j4-446m-qrf6 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-56j4-446m-qrf6 can be triaged on real exposure rather than presence alone.

Tailored to GHSA-56j4-446m-qrf6. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
