Why Cursor Keeps Writing Prototype Pollution Into Your JS

1. 1Identify potential recursive merge patterns in your code
2. 2Use structuredClone() to safely merge objects
3. 3Implement key blocklist guards to prevent prototype pollution
4. 4Test your code for vulnerabilities using tools like npm audit
5. 5Refactor your config merge utility to avoid recursive merges

Developers and security teams can benefit from understanding this issue to prevent prototype pollution vulnerabilities in their JavaScript applications

💡 Recursive merge patterns in JavaScript can lead to prototype pollution vulnerabilities, which can be exploited by attackers to inject properties onto Object.prototype
