Lightning components can use public Apex controllers from installed packages even if they are not global.

Have a public Apex class in a package and I install it in a subscriber org.
If you try to access this class in the subscriber org you get Compile Error: Type is not visible. As expected since the class is not global.

However, you will be able to call its methods if this class is the controller of a Lightning component created in the subscriber org. This is a not expected behavior.

1)In a Dev org set the namespace to SecIssue and create a managed package.

2) Add to the managed package the following 2 Apex Classes:
public class ApexPublicController {
@AuraEnabled public static String getSomething() {return 'HelloFromPublicApex'; }

public class ApexPublicControllerTest {
static testMethod void myTest() {ApexPublicController.getSomething() ;}

3) Upload a version of the managed package and copy its install url

4) Install the managed package in a Subscriber org

5) Verify that in the subscriber org you cannot invoke the public method: for instance if you create this Apex class:
public class ApexInSub {
public static String getSomething() {return SecIssue.ApexPublicController.getSomething() ; }
You will get: Error: Compile Error: Type is not visible: apexpubliccontroller at line 2 column 38

6) Create a Lightning component:
<aura:component controller='SecIssue.ApexPublicController' implements='flexipage:availableForAllPageTypes' access='global'>
<ui:button label="Call server" press="{!c.echo}"/>

7) paste the following in the controlller
echo : function(cmp) {
var action = cmp.get("c.getSomething");
action.setCallback(this, function(response) {
var state = response.getState();
if (state === "SUCCESS") {
} else {
console.log("Unknown error");

8) You can test this component (for instance adding it to a Lightning page using the App builder) and you can verity that when you press the button the alert with text "HelloFromPublicApex" is shown

Expected Behavior:
According to documentation: "The public access modifier declares that this class is visible in your application or namespace" but currently namespace can be used it from a different organization as shown in the example above.


Is it Fixed?
