CVE-2024-51755: Twig has unguarded calls to `__isset()` and to array-accesses when the sandbox is enabled
(updated )
In a sandbox, and attacker can access attributes of Array-like objects as they were not checked by the security policy.
They are now checked via the property policy and the __isset() method is now called after the security check.
This is a BC break.
