How to Fix GHSA-j34v-3552-5r7j

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

github.com/pomerium/pomerium fixed: 0.16.4 
Upgrade github.com/pomerium/pomerium to 0.16.4
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 github.com/pomerium/pomerium

How to Check if You Are Affected

To determine whether your application is affected by GHSA-j34v-3552-5r7j, inspect your project dependencies for Github.com/pomerium/pomerium:

inspect dependencies for github.com/pomerium/pomerium
