What you need to know about prototype pollution and how it affects JavaScript
No, this is not about solid waste generated with the production of prototypes or models for different products. Prototype pollution here refers to a critical cyber threat rated 10/10 on the CVSS scale of severity.
In a paper published in July this year, entitled "Silent Spring: Prototype Pollution Leads to Remote Code Execution in Node.js," security researchers revealed a serious vulnerability that affects prototype-based languages like JavaScript and the Node.js platform. This threat involves injecting properties into an object's root prototype at runtime and causes the execution of legit code gadgets.
