How to Fix GHSA-9gp7-6833-wv89

To remediate this vulnerability, upgrade all affected Go.etcd.io/etcd/client/v3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

go.etcd.io/etcd/client/v3 fixed: 3.4.10 
Upgrade go.etcd.io/etcd/client/v3 to 3.4.10
go.etcd.io/etcd/client/v3 fixed: 3.3.23 
Upgrade go.etcd.io/etcd/client/v3 to 3.3.23
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for go.etcd.io/etcd/client/v3

How to Check if You Are Affected

To determine whether your application is affected by GHSA-9gp7-6833-wv89, inspect your project dependencies for Go.etcd.io/etcd/client/v3:

inspect dependencies for go.etcd.io/etcd/client/v3

Analyze the terminal output to locate any version of Go.etcd.io/etcd/client/v3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.4.10), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.
