CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-19507

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: No


The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can use a specially crafted json, bypass "compareCommon()", and manipulate the type detection result, because certain internal attributes can be overwritten via a conflicting name, as demonstrated by 'constructor': {'name':'Array'}.
