GMS-2020-542: Prototype Pollution in unflatten

September 4, 2020 (updated October 1, 2021)

All versions of unflatten are vulnerable to prototype pollution. The function unflatten does not restrict the modification of an Object’s prototype, which may allow an attacker to add or modify an existing property that will exist on all objects.

No fix is currently available. Consider using an alternative package until a fix is made available.
