GHSA-qjcv-rx3v-7mvj affects the following packages: github.com/cosmos/ibc-go/v7 (Go), github.com/cosmos/ibc-go/v6 (Go), github.com/cosmos/ibc-go/v5 (Go), github.com/cosmos/ibc-go/v5 (Go), github.com/cosmos/ibc-go/v4 (Go), github.com/cosmos/ibc-go/v4 (Go), github.com/cosmos/ibc-go/v4 (Go), github.com/cosmos/ibc-go/v4 (Go), and 3 more. Ecosystems affected: Go.

How do I fix GHSA-qjcv-rx3v-7mvj?

Update github.com/cosmos/ibc-go/v7 to 7.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qjcv-rx3v-7mvj is resolved across your whole dependency graph.

How do I detect GHSA-qjcv-rx3v-7mvj in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/cosmos/ibc-go/v7, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-qjcv-rx3v-7mvj 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.

Is GHSA-qjcv-rx3v-7mvj actively exploited in the wild?

No public exploit code has been indexed for GHSA-qjcv-rx3v-7mvj 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.

When was GHSA-qjcv-rx3v-7mvj published, and has it been updated?

GHSA-qjcv-rx3v-7mvj was published on May 20, 2024 and was last updated on May 23, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
