- 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++.
Recommended action: Upgrade to 3.0.1 or 2.0.1 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
