CVE-2019-20149 Vulnerability in kind-of 6.0.2 #32

Closed ashergarland closed 4 years ago

ashergarland commented 4 years ago

ctorName in index.js in kind-of v6.0.2 allows external user input to overwrite certain internal attributes via a conflicting name, as demonstrated by 'constructor': {'name':'Symbol'}. Hence, a crafted payload can overwrite this builtin attribute to manipulate the type detection result.
