Hi,

The following vulnerability was published for restrictedpython.

CVE-2023-37271[0]:
| RestrictedPython is a tool that helps to define a subset of the
| Python language which allows users to provide a program input into a
| trusted environment. RestrictedPython does not check access to stack
| frames and their attributes. Stack frames are accessible within at
| least generators and generator expressions, which are allowed inside
| RestrictedPython. Prior to versions 6.1 and 5.3, an attacker with
| access to a RestrictedPython environment can write code that gets
| the current stack frame in a generator and then walk the stack all
| the way beyond the RestrictedPython invocation boundary, thus
| breaking out of the restricted sandbox and potentially allowing
| arbitrary code execution in the Python interpreter. All
| RestrictedPython deployments that allow untrusted users to write
| Python code in the RestrictedPython environment are at risk. In
| terms of Zope and Plone, this would mean deployments where the
| administrator allows untrusted users to create and/or edit objects
| of type `Script (Python)`, `DTML Method`, `DTML Document` or `Zope
| Page Template`. This is a non-default configuration and likely to be
| extremely rare. The problem has been fixed in versions 6.1 and 5.3.
