SCA: security update for AccessControl, Zope (GHSA-8xv7-89vj-q48c)

high Tenable Cloud Security Plugin ID 412940

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- AccessControl provides a general security framework for use in Zope. Python's "format" functionality
allows someone controlling the format string to "read" objects accessible (recursively) via attribute
access and subscription from accessible objects. Those attribute accesses and subscriptions use Python's
full blown `getattr` and `getitem`, not the policy restricted `AccessControl` variants `_getattr_` and
`_getitem_`. This can lead to critical information disclosure. `AccessControl` already provides a safe
variant for `str.format` and denies access to `string.Formatter`. However, `str.format_map` is still
unsafe. Affected are all users who allow untrusted users to create `AccessControl` controlled Python code
and execute it. A fix has been introduced in versions 4.4, 5.8 and 6.2. Users are advised to upgrade.
There are no known workarounds for this vulnerability. (CVE-2023-41050)
