Overview
Affected versions of this package are vulnerable to Improper Authentication through the AadOidcIdTokenDecoderFactory and AadB2cOidcIdTokenDecoderFactory OIDC ID token decoders in the Spring Cloud Azure OAuth2 login components. An attacker can elevate privileges and sign in as an unauthorized tenant user by supplying a forged or tenant-mismatched ID token that is signed correctly but has an unvalidated iss claim and, in AAD multi-tenant flows, an inconsistent tid claim. This allows unauthorized access to applications that rely on the issuer or tenant claims to restrict which identities may authenticate.
