golang.org/x/net fixed: 0.7.0 
Upgrade golang.org/x/net to 0.7.0
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 golang.org/x/net

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-41723, inspect your project dependencies for Golang.org/x/net:

inspect dependencies for golang.org/x/net

Analyze the terminal output to locate any version of Golang.org/x/net in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.0), your application is affected.

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