Description

Impact When the `++api++` traverser is accidentally used multiple times in a url, handling it takes increasingly longer, making the server less responsive. Patches Patches will be released in `plone.rest` 2.0.1 and 3.0.1. Series 1.x is not affected. Workarounds In your frontend web server (nginx, Apache) you can redirect `/++api++/++api++` to `/++api++`.
