Summary

Improperly Controlled Modification of Dynamically-Determined Object Attributes in express-mock-middleware

Details

express-mock-middleware through 0.0.6 is vulnerable to Prototype Pollution. Exported functions by the package can be tricked into adding or modifying properties of the Object.prototype. Exploitation of this vulnerability requires creation of a new directory where an attack code can be placed which will then be exported by express-mock-middleware. As such, this is considered to be a low risk.

Severity ?

5.3 (Medium)
