Technical details
An authentication bypass exists in Nhost's OAuth implementation where the system automatically merges identities based on email addresses without verifying that the email has been confirmed by the provider. The root cause is twofold: the central controller (`providerFlowSignIn`) fails to check the `EmailVerified` flag, and several provider adapters (Discord, Bitbucket, AzureAD, EntraID) incorrectly populate this flag by either ignoring provider-supplied verification status or falling back to unverified fields like UPN. An attacker can register an account with a target's email on a vulnerable provider, leave it unverified, and then use that provider to sign into Nhost, gaining a full authenticated session as the victim. A patch is available in version 0.0.0-20260417112436-ec8dab3f2cf4.
