SCA: security update for getgrav/grav (GHSA-whr7-m3f8-mpm8)

high Tenable Self-Hosted Container Security Plugin ID 419949

Description

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

 - Grav is a flat-file content management system. Prior to version 1.7.42, the patch for CVE-2022-2073, a
 server-side template injection vulnerability in Grav leveraging the default `filter()` function, did not
 block other built-in functions exposed by Twig's Core Extension that could be used to invoke arbitrary
 unsafe functions, thereby allowing for remote code execution. A patch in version 1.74.2 overrides the
 built-in Twig `map()` and `reduce()` filter functions in
 `system/src/Grav/Common/Twig/Extension/GravExtension.php` to validate the argument passed to the filter in
 `$arrow`. (CVE-2023-34448)
