How do security teams know if package publishing access is too broad?

Publishing access is too broad when more identities can release code than can explain, review, or revoke that release. Warning signs include shared maintainer accounts, long-lived tokens, unmanaged publish permissions, and no clear offboarding process when contributors leave. If release rights outlive accountability, the control is already weak.

Why This Matters for Security Teams

Package publishing access is effectively release authority. When too many identities can publish, a team loses confidence in who can ship code, who can retract it, and who can be held accountable after a compromise. That risk is amplified when access is granted through shared maintainer accounts, long-lived API tokens, or CI/CD secrets that outlive the people and pipelines they were meant to support. The OWASP Non-Human Identity Top 10 treats these as identity and lifecycle failures, not just build hygiene issues.

For practitioners, the warning sign is not merely whether publishing works, but whether it can be explained, limited, and revoked with precision. NHI Management Group research shows that excessive privilege is pervasive across non-human identities, and that visibility gaps remain common in real environments, especially where release tooling is inherited from older CI/CD patterns. In practice, many security teams discover overbroad package publishing only after an unexpected release, a credential leak, or an offboarding event has already exposed the gap.

How It Works in Practice

The safest way to evaluate publishing scope is to trace the full release path: who can prepare a package, who can sign or approve it, who can publish it, and who can revoke that ability. If those steps collapse into one identity, or if multiple people share one credential, the publishing control is too broad even if the package registry technically supports permissions. The issue is accountability, not just access.

Teams should look for these concrete indicators:

• One token can publish to production packages without a separate approval step.
• Publish permissions are granted to broad developer groups instead of specific release operators.
• Service accounts and CI jobs can publish indefinitely without rotation or expiration.
• Offboarding does not automatically remove registry rights or revoke cached credentials.
• No one can quickly answer which identity published the last release and under what approval context.

Control design should align with least privilege, short-lived secrets, and clear ownership. The Ultimate Guide to NHIs notes that only 20% of organisations have formal offboarding and API key revocation processes, which helps explain why publishing access often drifts wider over time. Where release automation is required, publish rights should be issued just in time, tied to workload identity, and revoked after the task completes. The LiteLLM PyPI package breach is a reminder that publishing abuse can become a distribution problem fast when secrets and release authority are not tightly separated. These controls tend to break down in distributed CI/CD estates because multiple pipelines, registries, and maintainers each hold partial release power.

Common Variations and Edge Cases

Tighter publishing controls often increase release friction, requiring organisations to balance velocity against accountability. That tradeoff is real, especially for open source maintainers, federated engineering teams, and high-frequency delivery pipelines where a human approval at every step may not be practical.

Best practice is evolving, but current guidance suggests treating package publishing as a privileged action with distinct authorization, not a routine developer permission. In some environments, a single maintainer may legitimately publish during early-stage development, but that exception should be temporary, documented, and reviewed. In regulated or high-impact software, the stronger pattern is separate build, review, and publish identities with time-bound access and full auditability.

Edge cases also matter. Third-party release automation, delegated maintainership, and emergency hotfix publishing can all justify broader access for short windows, but those windows should be explicit and monitored. The State of Non-Human Identity Security highlights how over-privileged accounts and weak monitoring remain common causes of NHI incidents, which makes temporary exceptions risky unless they are tightly controlled. If a team cannot distinguish normal publishing from exceptional publishing in logs and ownership records, the access model is already too broad.
