Access Control: Unenforced Sharing Rules

Abstract
Apex 클래스에는 사용자 공유 규칙을 적용하지 않고 실행할 수 있는 데이터베이스 작업이 포함되어 있습니다.
Explanation
Salesforce 응용 프로그램은 공유 규칙을 사용하여 사용자 권한 및 데이터베이스 레코드에 대한 액세스를 제어합니다. 그러나 Apex에서 사용자 공유 규칙이 항상 적용되는 것은 아닙니다. 규칙이 적용되는 방식을 변경하는 다른 공유 키워드를 사용하여 Apex 클래스를 선언할 수 있기 때문입니다. 다음의 세 가지 공유 키워드 중 하나로 클래스를 선언할 수 있습니다.
- with sharing: 사용자 공유 규칙이 적용됩니다.
- without sharing: 공유 규칙이 적용되지 않습니다.
- inherited sharing: 호출 클래스의 공유 규칙이 적용됩니다. 호출 클래스가 공유 키워드를 지정하지 않거나 클래스 자체가 Visualforce 컨트롤러와 같은 진입점인 경우에는 사용자 공유 규칙이 기본적으로 적용됩니다.
공유 키워드가 선언되어 있지 않으면 클래스는 호출 클래스의 공유 모드(있는 경우)를 상속합니다. 그 외의 경우에는 공유 규칙이 적용되지 않습니다.
예제 1: 다음 3개 Apex 클래스에는 모두 데이터베이스 쿼리 호출용으로 안전하지 않은 공유 키워드가 포함되어 있습니다.

public class TestClass1 {
public List<Contact> getAllTheSecrets() {
return Database.query('SELECT Name FROM Contact');
}
}
public without sharing class TestClass2 {
public List<Contact> getAllTheSecrets() {
return Database.query('SELECT Name FROM Contact');
}
}
public inherited sharing class TestClass3 {
public List<Contact> getAllTheSecrets() {
return Database.query('SELECT Name FROM Contact');
}
}
TestClass1TestClass2가 안전하지 않은 이유는 사용자 공유 규칙을 적용하지 않고도 레코드를 검색할 수 있기 때문입니다.
TestClass3 의 경우에는 기본적으로 공유 규칙을 적용하므로 더 안전합니다. 그러나 without sharing을 명시적으로 선언하는 클래스에서 getAllTheSecrets() 함수를 호출하는 경우에는 여전히 무단 액세스 권한을 부여할 수 있습니다.
