plone.rest vulnerable to Denial of Service when ++api++ is used many times
Impact
When the ++api++ traverser is accidentally used multiple times in a url, handling it takes increasingly longer, making the server less responsive.

Workarounds
In your frontend web server (nginx, Apache) you can redirect /++api++/++api++ to /++api++.
