CVE-2021-29491: Improper Control of Dynamically-Managed Code Resources

Mixme is a library for recursive merging of Javascript objects. In Node.js mixme, an attacker can add or alter properties of an object via proto through the mutate() and merge() functions. The polluted attribute will be directly assigned to every object in the program. This will put the availability of the program at risk causing a potential denial of service (DoS).
