A PoC/exploit has been discovered for vulnerability CVE-2026-28695 PT ID: PT-2026-22947 Vendor: Craft Product: Craft CMS Description: Craft is a content management system (CMS). There is an authenticated admin RCE in Craft CMS 5.8.21 via Server-Side Template Injection using the create() Twig function combined with a Symfony Process gadget chain. The create() Twig function exposes Craft::createObject(), which allows instantiation of arbitrary PHP classes with constructor arguments. Combined with the bundled symfony/process dependency, this enables RCE. This bypasses the fix implemented for CVE-2025-57811 (patched in 5.8.7). This vulnerability is fixed in 5.9.0-beta.1 and 4.17.0-beta.1. References: • https://dbu.gs/vulnerability/PT-2026-22947 • https://github.com/predyy/cve-2026-28695
