CVE-2023-42457 Information

Description

plone.rest allows users to use HTTP verbs such as GET POST PUT DELETE etc. in Plone. Starting in the 2.x branch and prior to versions 2.0.1 and 3.0.1 when the ++api++ traverser is accidentally used multiple times in a url handling it takes increasingly longer making the server less responsive. Patches are available in plone.rest 2.0.1 and 3.0.1. Series 1.x is not affected. As a workaround one may redirect /++api++/++api++ to /++api++ in one’s frontend web server (nginx Apache).
