Which @angular/* package(s) are the source of the bug?
compiler
Is this a regression?
Yes
Description
Following #70188, released in Angular 22.2.0, the template can access private members of its corresponding class. That's fine (although opinions might differ). But the template can also access the private member of the class' parent, which are very much not fine at all.
If the child class (correctly) cannot access the parent class private members, then the child template should not be able to access the parent class private members.
Minimum reproduction:
import { bootstrapApplication } from '@angular/platform-browser';
import { Component, signal } from '@angular/core';
export class Parent {
private readonly parent = signal('from parent');
}
@Component({
selector: 'app-root',
template: `
<p>Hello, {{ parent() }} - This works since Angular 22.2 and it should not !</p>
<p>Hello, {{ child() }}</p>
`,
})
export class App extends Parent {
private readonly child = signal('from child');
constructor() {
super();
// console.log(this.parent()); // This still does not work and should never work
}
}
bootstrapApplication(App);Please provide a link to a minimal reproduction of the bug

Please provide the exception or error you saw
No exception, but I expect to see something like "Property 'parent' is private and only accessible within class".
