github.com/cosmos/ibc-go affected by IBC protocol "Huckleberry" vulnerability
What to do
Partial vendor fix. Follow the primary source's mitigation guidance and check back for a fix.
This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: GHSA-qjcv-rx3v-7mvj Advisory: github.com/cosmos/ibc-go affected by IBC protocol "Huckleberry" vulnerability IDs: GHSA-qjcv-rx3v-7mvj Record: https://patchnext.com/advisories/ghsa-qjcv-rx3v-7mvj (revision 1, source checked 26 Oct 2026, 15:04 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: Unrated Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Partial vendor fix; fixed versions by package: github.com/cosmos/ibc-go/v7 7.0.1; github.com/cosmos/ibc-go/v5 5.3.1, 5.2.1; github.com/cosmos/ibc-go/v4 4.4.1, 4.3.1, 4.2.2, 4.1.3; github.com/cosmos/ibc-go/v6 6.1.1. A vendor fix does not mean a deployment is fixed. ## Affected components - Go github.com/cosmos/ibc-go/v7: affected < 7.0.1; fixed in 7.0.1 - Go github.com/cosmos/ibc-go/v5: affected < 5.2.1; >= 5.3.0, < 5.3.1; fixed in 5.2.1, 5.3.1 - Go github.com/cosmos/ibc-go/v3: affected <= 3.4.0 - Go github.com/cosmos/ibc-go/v4: affected < 4.1.3; >= 4.2.0, < 4.2.2; >= 4.3.0, < 4.3.1; >= 4.4.0, < 4.4.1; fixed in 4.4.1, 4.1.3, 4.3.1, 4.2.2 - Go github.com/cosmos/ibc-go/v6: affected < 6.1.1; fixed in 6.1.1 - Go github.com/cosmos/ibc-go: affected <= 1.5.0 - Go github.com/cosmos/ibc-go/v2: affected <= 2.5.0 ## Suggested inspection (read-only) - Go github.com/cosmos/ibc-go/v7: check the installed version with your package manager. - Go github.com/cosmos/ibc-go/v5: check the installed version with your package manager. - Go github.com/cosmos/ibc-go/v3: check the installed version with your package manager. - Go github.com/cosmos/ibc-go/v4: check the installed version with your package manager. - Go github.com/cosmos/ibc-go/v6: check the installed version with your package manager. - Go github.com/cosmos/ibc-go: check the installed version with your package manager. - Go github.com/cosmos/ibc-go/v2: check the installed version with your package manager. ## Supported action No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything. ## Required regression checks - Run the test suite and a production build. - Exercise the features that depend on github.com/cosmos/ibc-go/v7, github.com/cosmos/ibc-go/v5, github.com/cosmos/ibc-go/v3, github.com/cosmos/ibc-go/v4, github.com/cosmos/ibc-go/v6, github.com/cosmos/ibc-go, github.com/cosmos/ibc-go/v2. - Repeat the inspection and confirm that only fixed versions remain installed. ## Rollback considerations - Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward. ## Unresolved questions - Which deployments run an affected version? - Exploitation status can change. Check again before lowering the priority. - Mark the work resolved only after the fixed version is verified in production. ## Sources - Verified: https://github.com/advisories/GHSA-qjcv-rx3v-7mvj (GitHub-reviewed advisory GHSA-qjcv-rx3v-7mvj lists affected ranges: Go github.com/cosmos/ibc-go/v7 >=0 =0 =0 =5.3.0 =0 =4.2.0 =4.3.0 =4.4.0 =0 =0 =0 <=1.5.0) Commands are suggestions: review each one before running it.
