Vulnerability details
The vulnerability allows an unauthenticated remote attacker to identify email addresses associated with pending invited accounts on a NocoDB instance.
The vulnerability exists due to the sign-in endpoint returning a distinct error when an invited account has not completed signup, rather than the generic invalid-credentials error. An unauthenticated remote attacker can submit an email address with an incorrect password and recognize the invitation-specific response to confirm account existence.
