A prototype pollution vulnerability was found in module extend <2.0.2, ~<3.0.2 that allows an attacker to inject arbitrary properties onto Object.prototype.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
