Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Hail (PyPI package hail, versions before 0.2.127) relies on email claims from OIDC identity providers to verify that a user belongs to an organization's domain. An attacker with a Microsoft or Google account that can set an arbitrary email address, or an Azure AD administrator, can create Hail Batch accounts on clusters whose organization domain they do not belong to, and can run jobs if trial billing projects are enabled. Upgrade to hail 0.2.127 or later, and audit the user list for accounts whose login IDs are not valid with your identity provider.
