The author argues that GitHub Actions should allow end-users to specify audience constraints for OIDC tokens, preventing attackers from pivoting across services that use independent OIDC-bearing jobs. While GitLab CI/CD already supports audience scoping via the aud field, GitHub Actions currently lacks this capability, creating a growing security risk as more workflows federate with third-party services.
Background
OIDC tokens in CI/CD pipelines enable secure federated authentication with cloud providers and package registries without exposing long-lived credentials. GitHub Actions has become one of the most widely adopted CI/CD platforms, making any security improvement to its OIDC implementation broadly impactful.
