Technical details
The initConnection GraphQL mutation fails to enforce datasource-edit authorization checks before allowing saveCredentials and sharedCredentials flags to be set with arbitrary authProperties. An attacker with view-only shared-project access can exploit this to persist credentials and shared connection configurations, causing subsequent users connecting to the shared connection to authenticate under the attacker's database identity. This is a privilege escalation attack that enables lateral movement and credential theft in multi-tenant database environments.
