GHSA-rj53-j6jw-7f7g
Babylon vulnerable to chain halt when a message modifies the validator set at the epoch boundary
Blast Radius

Description
Summary
Sending a message that modifies the validator set at the epoch boundary halts the chain.
Impact
Denial of Service - Comos-sdk prevents modifying the validator set from two different modules - https://github.com/cosmos/cosmos-sdk/blob/release/v0.50.x/types/module/module.go#L811. Such an operation leads to panic and chain halt.
Detailed Post mortem
Affected Packages

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/v2. 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/v2 to 2.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rj53-j6jw-7f7g 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-rj53-j6jw-7f7g 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-rj53-j6jw-7f7g. 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-rj53-j6jw-7f7g in your dependencies?
O3 detects GHSA-rj53-j6jw-7f7g across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
