What serious security threats are there that solely rely on the client JavaScript code that the browser allows? One risk are buggy implementations which can be used to crash the browser or execute code by using heap spraying attacks or similar. These can be kind of mitigated within modern browsers by using ASLR, DEP, sandboxes and similar ...

By implementing robust input validation, you can effectively preempt common vulnerabilities like Cross-Site Scripting (XSS) attacks.
- Steering Clear of Eval() Utilizing the eval() function has emerged as a significant security hazard, given its potential to execute arbitrary code, thereby enabling code injection vulnerabilities.
- Preventing Cross-Site Scripting (XSS) Cross-Site Scripting (XSS) incidents occur when untrusted data is rendered in browsers without adequate escape measures.
- Safeguarding Against Cross-Site Request Forgery (CSRF) To avert CSRF attacks, your JavaScript applications must integrate robust CSRF protection mechanisms.
