# Unvalidated npm trusted publishing configurations now expire

Markdown version of <https://harbyn.com/changes/npm/2026-10-02-unvalidated-npm-trusted-publishing-configurations-now-expire>.

Breaking change - npm. medium severity. In effect.

Unvalidated npm trusted publishing configurations now expire 48 hours after creation and can no longer authorize publishing; a configuration becomes validated and exempt after its first successful publish. npm also now rejects trusted publishing tokens from GitHub Actions issue\_comment events, like pull\_request\_target; workflows that publish on issue\_comment must move to push, release or workflow\_dispatch.
