SCA: security update for craftcms/cms (GHSA-gp2f-7wcm-5fhx)

high Tenable Cloud Security Plugin ID 437934

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 performs DNS resolution separately from
 the HTTP request. This Time-of-Check-Time-of-Use (TOCTOU) vulnerability enables DNS rebinding attacks,
 where an attacker’s DNS server returns different IP addresses for validation compared to the actual
 request. This is a bypass of the security fix for CVE-2025-68437 that allows access to all blocked IPs,
 not just IPv6 endpoints. 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. (CVE-2026-27127)
