plone4.csrffixes 1.0.8

CSRF fixes for Plone 4

plone4.csrffixes

The package aims to backport the auto CSRF implementation from Plone 5 to Plone 4.

The reason this is necessary is because there are a lot of CSRF problem with the ZMI that Zope2 will never be able to fix.

See https://plone.org/products/plone/security/advisories/security-vulnerability-20151006-csrf for more details.

Installation

Plone 4.3, 4.2, 4.1 and 4.0

add plone4.csrffixes to eggs list:

eggs =
    ...
    plone4.csrffixes
    ...

add a new version pin for plone.protect, plone.keyring and plone.locking:

[versions]
...
plone.keyring = 3.0.1
plone.locking = 2.0.8
plone.protect = 3.0.16
...

Plone 4.0 and 4.1

If lxml is not already included in your site, this package has a dependency on lxml and will pull it in when installed.

We recommend pinning to version 2.3.6 of lxml. If you use a version of lxml > 3, you’ll need to also install the cssselect package. Since version 1.0.4 we require cssselect in our setup.py so it is automatically installed.

Additional addon versions

To prevent some write on read errors that might cause false positives with the auto csrf protection, these version pins have been reported to work upgrading to:

Products.CMFQuickInstallerTool = 3.0.12
Products.PlonePAS = 5.0.4
