Description

In jpv (aka Json Pattern Validator) before 2.1.1, compareCommon() can be bypassed because certain internal attributes can be overwritten via a conflicting name, as demonstrated by constructor: {name:Array}. This affects validate(). Hence, a crafted payload can overwrite this builtin attribute to manipulate the type detection result.
