Description

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
