In a sandbox, an attacker can call __toString() on an object even if the __toString() method is not allowed by the security policy when the object is part of an array or an argument list (arguments to a function or a filter for instance).
Resolution
The sandbox mode now checks the __toString() method call on all objects.
The patch for this issue is available here for branch 3.x.

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.
