Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in nodejs-kind-of. An external user is allowed 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.

Description Sam Fowler 2021-05-12 08:09:25 UTC 
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.

Comment 1 Sam Fowler 2021-05-12 08:10:35 UTC 
Created nodejs-kind-of tracking bugs for this issue:

Affects: fedora-all [bug 1959722]
Comment 4 Jason Shepherd 2021-05-13 01:11:55 UTC 
Versions of `kind-of` 6.x prior to 6.0.3 are vulnerable.
Comment 7 Tapas Jena 2021-05-14 18:26:03 UTC 
Analysis is complete for AAP components and as a result, I found that though its uses the vulnerable version of nodeJS kind-of lib, none of the components seem to be using the ctorName functionality in index.js or kind-of / kindOf functionality for type checking. Hence, lowering the severity from medium to low.
