SCA: security update for october/cms (GHSA-fcr8-6q7r-m4wg)

medium Tenable Cloud Security Plugin ID 414453

Description

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

- October is a free, open-source, self-hosted CMS platform based on the Laravel PHP Framework. A bypass of
CVE-2020-26231 (fixed in 1.0.470/471 and 1.1.1) was discovered that has the same impact as CVE-2020-26231
& CVE-2020-15247. An authenticated backend user with the `cms.manage_pages`, `cms.manage_layouts`, or
`cms.manage_partials` permissions who would **normally** not be permitted to provide PHP code to be
executed by the CMS due to `cms.enableSafeMode` being enabled is able to write specific Twig code to
escape the Twig sandbox and execute arbitrary PHP. This is not a problem for anyone that trusts their
users with those permissions to normally write & manage PHP within the CMS by not having
`cms.enableSafeMode` enabled, but would be a problem for anyone relying on `cms.enableSafeMode` to ensure
that users with those permissions in production do not have access to write & execute arbitrary PHP. Issue
has been patched in Build 472 (v1.0.472) and v1.1.2. As a workaround, apply
https://github.com/octobercms/october/commit/f63519ff1e8d375df30deba63156a2fc97aa9ee7 to your installation
manually if unable to upgrade to Build 472 or v1.1.2. (CVE-2021-21264)
