summary: Incorrect email domain verification in github.com/coder/coder
description: |-
    A vulnerability in Coder's OIDC authentication could allow an attacker to bypass
    the CODER_OIDC_EMAIL_DOMAIN verification and create an account with an email
    not in the allowlist. Deployments are only affected if the OIDC provider allows
    users to create accounts on the provider (such as public providers like
    google.com). During OIDC registration, the user's email was improperly
    validated against the allowed CODER_OIDC_EMAIL_DOMAINs.
