Summary
goreleaser shows environment by default
Details

Summary

Since #4787 the log output is printed on the INFO level, while previously it was logged on DEBUG. This means if the go build output is non-empty, goreleaser leaks the environment.

PoC

  • Create a Go project with dependencies, do not pull them yet (or run goreleaser later in a container, or delete $GOPATH/pkg).
  • Make sure to have secrets set in the environment
  • Make sure to not have go mod tidy in a before hook
  • Run goreleaser release --clean
  • Go prints lots of go: downloading ... lines, which triggers the "if output not empty, log it" line, which includes the environment.

Impact

Credentials and tokens are leaked.

Severity
