CVE-2023-36814 – zopefoundation's Products.CMFCore vulnerable to unauthenticated denial of service and crash via unchecked use of input with Python's marshal module

https://notcve.org/view.php?id=CVE-2023-36814

Products.CMFCore are the key framework services for the Zope Content Management Framework (CMF). The use of Python's marshal module to handle unchecked input in a public method on `PortalFolder` objects can lead to an unauthenticated denial of service and crash situation. The code in question is exposed by all portal software built on top of `Products.CMFCore`, such as Plone. All deployments are vulnerable. The code has been fixed in `Products.CMFCore` version 3.2. • https://github.com/zopefoundation/Products.CMFCore/commit/40f03f43a60f28ca9485c8ef429efef729be54e5 https://github.com/zopefoundation/Products.CMFCore/security/advisories/GHSA-4hpj-8rhv-9x87 • CWE-770: Allocation of Resources Without Limits or Throttling •
