== Sensitive Code Example

----
@RequestMapping("/delete_user")  // Sensitive: by default all HTTP methods are allowed
public String delete1(String username) {
// state of the application will be changed here
}

@RequestMapping(path = "/delete_user", method = {RequestMethod.GET, RequestMethod.POST}) // Sensitive: both safe and unsafe methods are allowed
String delete2(@RequestParam("id") String id) {
// state of the application will be changed here
}
----

== Compliant Solution

[source,java]
----
@RequestMapping("/delete_user", method = RequestMethod.POST)  // Compliant
public String delete1(String username) {
// state of the application will be changed here
}

@RequestMapping(path = "/delete_user", method = RequestMethod.POST) // Compliant
String delete2(@RequestParam("id") String id) {
// state of the application will be changed here
}
