{"id":"CVE-2026-28695","aliases":["GHSA-94rc-cqvm-m4pw"],"url":"https://o3.security/vulnerability/CVE-2026-28695","summary":"Craft affected by authenticated RCE via Twig SSTI - create() function + Symfony Process gadget","details":"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.","published":"2026-03-04T16:15:32.556Z","modified":"2026-08-07T11:50:15.198177116Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"craftcms/cms","fixedVersion":"5.9.0-beta.1"},{"ecosystem":"Packagist","name":"craftcms/cms","fixedVersion":"4.17.0-beta.1"}],"fix":{"url":"https://github.com/craftcms/cms/commit/e31e50849ad71638e11ea55fbd1ed90ae8f8f6e0","label":"craftcms/cms@e31e508"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28695.json"},{"type":"ADVISORY","url":"https://github.com/craftcms/cms/security/advisories/GHSA-94rc-cqvm-m4pw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28695"},{"type":"FIX","url":"https://github.com/craftcms/cms/commit/e31e50849ad71638e11ea55fbd1ed90ae8f8f6e0"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:15.198177116Z"}}
