Prototype pollution is a class of vulnerabilities in JavaScript runtimes that allows attackers to overwrite arbitrary properties in an object's prototype.^[1][2][3] In a prototype pollution attack, attackers inject properties into existing JavaScript construct prototypes, trying to compromise the application.
