SCA: security update for craftcms/cms (GHSA-v2gc-rm6g-wrw9)

high Tenable Cloud Security Plugin ID 437950

Description

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

 - Craft is a content management system (CMS). In versions 4.5.0-RC1 through 4.16.18 and 5.0.0-RC1 through
 5.8.22, the SSRF validation in Craft CMS’s GraphQL Asset mutation uses `gethostbyname()`, which only
 resolves IPv4 addresses. When a hostname has only AAAA (IPv6) records, the function returns the hostname
 string itself, causing the blocklist comparison to always fail and completely bypassing SSRF protection.
 This is a bypass of the security fix for CVE-2025-68437. Exploitation requires GraphQL schema permissions
 for editing assets in the `<VolumeName>` volume and creating assets in the `<VolumeName>` volume. These
 permissions may be granted to authenticated users with appropriate GraphQL schema access and/or Public
 Schema (if misconfigured with write permissions). Versions 4.16.19 and 5.8.23 patch the issue.
