…wondering if I need to do the same for and… probably (but not today)

I am a bit confused about this paragraph.

SQL quoting in DTML or in connection objects was insufficient, leading to possible SQL injections. This is a problem in Zope. If you use Zope without Plone, this hotfix should work for you too. Reported and fixed by Michael Brunnbauer and Michael Howitz.

You can read This is a problem in Zope.

Over at the Zope issue tracker ( ) you can read The one fix that mentions Zope fixes addon packages, not Zope itself.

So, could anybody (maybe @icemac who fixed the problem) tell me what package is affected? Thank you!

I created an issue in CMFPlone to track getting all the fixes in core:

The SQL quoting problem needs fixes in DocumentTemplate , Products.PythonScripts , and Products.ZSQLMethods (for Shared.DC.ZRDB.Connection ). Either I or someone else can prepare PRs. But the entire hotfix fixes six problems, divided over about ten packages, in various versions, so it can take a while.

And yes, I will be at the Alpine City Sprint, and Michael too, so we can talk.
