Doc Text:	A flaw was found in Grafana, which validates Azure AD accounts based on the email claim. On Azure AD, the profile email field is not unique across Azure AD tenants, which enables Grafana account takeover and authentication bypass when Azure AD OAuth is configured with a multi-tenant AzureAD OAuth application. This may allow an attacker to gain complete control of the user's account, including access to private customer data and sensitive information.	Story Points:	---

Description Anten Skrabec 2023-06-08 18:58:51 UTC

Grafana is validating Azure AD accounts based on the email claim. On Azure AD, the profile email field is not unique across Azure AD tenants. This enables Grafana account takeover and authentication bypass when Azure AD OAuth is configured with a multi-tenant AzureAD OAuth application. If exploited, the attacker can gain complete control of the user's account, including access to private customer data and sensitive information. All users in Grafana deployments with Azure AD OAuth configured with a multi-tenant Azure app and which do not have allowed_groups configured are affected and can be compromised.
