Affected: zopefoundation Products.CMFCore

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://cve.radiocsirt.org/vuln/ghsa-4hpj-8rhv-9x87 GHSA-4hpj-8rhv-9x87 — Products.CMFCore unauthenticated denial of service and crash via unchecked use of input with Python's marshal module 2026-10-03T03:05:24.135245+00:00

Affected: PyPI: Products.CMFCore

### Impact 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.

### Patches The code has been fixed in `Products.CMFCore` version 3.2.

### Workarounds Users can make the affected `decodeFolderFilter` method unreachable by editing the `PortalFolder.py` module in `Products.CMFCore` by hand and then restarting Zope. Go to line 233 of `PortalFolder.py` and remove both the `@security.public` decorator for `decodeFolderFilter` as well as the method's entire docstring. This is safe because the method is not actually used by current code.
