nodejs-kind-of: ctorName in index.js allows external user input to overwrite certain internal attributes

Dec 16, 2019
microsoft2019-Dec/CVE-2019-20149Important

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.
