SCA: security update for getkirby/cms (GHSA-x275-h9j4-7p4h)

medium Tenable Cloud Security Plugin ID 434754

Description

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

 - Kirby is an open-source content management system. A vulnerability in versions prior to 3.9.8.3, 3.10.1.2,
 and 4.7.1 affects all Kirby sites that use the `collection()` helper or `$kirby->collection()` method with
 a dynamic collection name (such as a collection name that depends on request or user data). Sites that
 only use fixed calls to the `collection()` helper/`$kirby->collection()` method (i.e. calls with a simple
 string for the collection name) are *not* affected. A missing path traversal check allowed attackers to
 navigate and access all files on the server that were accessible to the PHP process, including files
 outside of the collections root or even outside of the Kirby installation. PHP code within such files was
 executed. Such attacks first require an attack vector in the site code that is caused by dynamic
 collection names, such as `collection('tags-' . get('tags'))`. It generally also requires knowledge of the
 site structure and the server's file system by the attacker, although it can be possible to find
 vulnerable setups through automated methods such as fuzzing. In a vulnerable setup, this could cause
 damage to the confidentiality and integrity of the server. The problem has been patched in Kirby 3.9.8.3,
 Kirby 3.10.1.2, and Kirby 4.7.1. In all of the mentioned releases, the maintainers of Kirby have added a
 check for the collection path that ensures that the resulting path is contained within the configured
 collections root. Collection paths that point outside of the collections root will not be loaded.
