SCA: security update for AccessControl (GHSA-pq59-9fq7-m886)

medium Tenable Cloud Security Plugin ID 448259

Description

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

- Zope AccessControl provides a general security framework for use in Zope. Prior to 7.4, applications that
allow untrusted users to create and execute AccessControl-controlled Python code do not safely guard
str.format and str.format_map when those methods are reached through a str subclass. In both ImplPython.py
and cAccessControl.c, Python formatting can recursively access attributes and subscriptions using
unrestricted getattr and getitem behavior instead of the policy-restricted getattr and getitem operations.
A controlled format string can therefore disclose objects reachable from values available to the
formatting operation. This issue is fixed in version 7.4. (CVE-2026-77401)

Solution

Update the AccessControl library and its related packages to version 7.4 or later.
