This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Summary
The anti-slashing is not effective if the attacker can access EOTS manager endpoints.
Impact
If the EOTS manager endpoints are open to public without HMAC protection, the attacker can manually cause slashing of the finality provider through the RPC endpoints.

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/finality-provider. 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/finality-provider to 1.0.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4jmp-x7mh-rgmr 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-4jmp-x7mh-rgmr 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-4jmp-x7mh-rgmr. 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-4jmp-x7mh-rgmr in your dependencies?
O3 detects GHSA-4jmp-x7mh-rgmr across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
