{"id":"CVE-2026-92593","summary":"Craft CMS 5.10.0 before 5.10.13 Authenticated Remote Code Execution","details":"Craft CMS versions 5.10.0 through 5.10.12 contain an incomplete fix for CVE-2026-55794: the Controller::getPostedRedirectUrl() -\u003e View::renderObjectTemplate() sink remained unsandboxed, and the same fix commit added a self-signing oracle in Cp::elementLabelHtml(). Because Craft/Yii HMAC tokens are not bound to a parameter name, an authenticated low-privilege control panel user with edit rights on a single element type can mint a token over attacker-controlled Twig for the returnUrl parameter and replay it as the redirect POST parameter, reaching the unsandboxed sink and achieving server-side template injection that executes arbitrary PHP code (full server compromise). The issue is fixed in 5.10.13.","aliases":["GHSA-5jmw-g85v-7jv2"],"modified":"2026-09-19T03:30:43.152010181Z","published":"2026-09-16T21:46:58.692Z","database_specific":{"cwe_ids":["CWE-94"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92593.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92593.json"},{"type":"ADVISORY","url":"https://github.com/craftcms/cms/security/advisories/GHSA-5jmw-g85v-7jv2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92593"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/craft-cms-5.10.0-before-5.10.13-authenticated-remote-code-execution"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/craftcms/cms","events":[{"introduced":"a516a6190ba8ef39a7603863df9ae09eb89f3a64"},{"fixed":"0b18123e8c3be1edcf6f785e9925e1b1007ce8c5"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"5.10.0"},{"fixed":"5.10.13"},{"fixed":"5.10.12"}]}}],"versions":["5.10.12","5.10.11","5.10.10","5.10.9","5.10.8.1","5.10.8","5.10.7","5.10.6","5.10.5","5.10.4.1","5.10.4","5.10.3","5.10.2","5.10.1","5.10.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92593.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
