How do I fix GHSA-869w-47c6-fq8q?

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.

How do I detect GHSA-869w-47c6-fq8q in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/babylonlabs-io/babylon, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-869w-47c6-fq8q if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-869w-47c6-fq8q?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-869w-47c6-fq8q can be triaged on real exposure rather than presence alone.

Is GHSA-869w-47c6-fq8q actively exploited in the wild?

No public exploit code has been indexed for GHSA-869w-47c6-fq8q yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

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

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
