SCA: security update for craftcms/cms (GHSA-qc86-q28f-ggww)

high Tenable Self-Hosted Container Security Plugin ID 438322

Description

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

- Craft is a content management system (CMS). Prior to 5.8.22 and 4.16.18, it is possible to craft a
malicious payload using the Twig map filter in text fields that accept Twig input under Settings in the
Craft control panel or using the System Messages utility, which could lead to a RCE. For this to work, you
must have administrator access to the Craft Control Panel, and allowAdminChanges must be enabled for this
to work, which is against our recommendations for any non-dev environment. Alternatively, you can have a
non-administrator account with allowAdminChanges disabled, but you have access to the System Messages
utility. Users should update to the patched versions (5.8.22 and 4.16.18) to mitigate the issue.
(CVE-2026-28784)
