What did you do?

1. Generate a package-based Software Bill Of Materials (SBOM) and scan it for CVEs

$ zarf tools sbom packages --exclude './iam' . -o json | grype --fail-on low
 ✔ Indexed .               
 ✔ Cataloged packages      [1461 packages]
NAME              INSTALLED  FIXED-IN  TYPE       VULNERABILITY        SEVERITY 
golang.org/x/net  v0.15.0    0.17.0    go-module  GHSA-qppj-fm5r-hxr3  Medium    
golang.org/x/net  v0.15.0    0.17.0    go-module  GHSA-4374-p667-p6c8  Medium
1 error occurred:
        * discovered vulnerabilities at or above the severity threshold

2. Determine what dependency is using golang.org/x/net@v0.15.0

$ go mod graph | grep golang.org/x/net@v0.15.0
golang.org/x/tools@v0.13.0 golang.org/x/net@v0.15.0

What did you expect to see?

There is a released version of x/tools that uses x/net version v0.17.0

What did you see instead?

The current latest version of x/tools (v0.14.0) is on x/net version v0.16.0
