The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to sandbox information disclosure via the __toString() method call on an object that even can be disabled by the security policy in place. A remote attacker can gain unauthorized access to sensitive information on the system.
2) Security features bypass (CVE-ID: CVE-2022-23614)
CWE-ID: CWE-254 - Security Features
