GHSA-xq4h-wqm2-668w

GHSA-xq4h-wqm2-668w is a security vulnerability in github.com/babylonlabs-io/babylon/v4. O3 Security confirms whether GHSA-xq4h-wqm2-668w is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Babylon's BIP322 signature implementation is not fully compliant to the spec

Real-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

The BIP-322 signature verification does not enforce the SIGHASH value to be SIGHASH_ALL, and therefore is not strictly following the spec.

Impact

Non-compliant BIP-322 signatures in proof of possessions can be accepted by the chain.

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/v4. 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/v4 to 4.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xq4h-wqm2-668w 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-xq4h-wqm2-668w 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-xq4h-wqm2-668w. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
