{"id":"CVE-2026-64665","aliases":["GHSA-93qh-5269-9wcf"],"url":"https://o3.security/vulnerability/CVE-2026-64665","summary":"Statamic: Account takeover via OAuth email matching without email-verification check","details":"Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.74.1 and 6.24.0, when OAuth login was enabled with a provider that does not guarantee verified email addresses, an unauthenticated attacker could sign in as an existing user, potentially including a super admin, without knowing that user's password, because the application matched OAuth identities to accounts by email address alone. Exploitation requires OAuth to be explicitly enabled with such a provider. This issue is fixed in versions 5.74.1 and 6.24.0.","published":"2026-08-06T19:25:01.756Z","modified":"2026-09-10T03:31:02.321258892Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"statamic/cms","fixedVersion":"5.74.1"},{"ecosystem":"Packagist","name":"statamic/cms","fixedVersion":"6.24.0"}],"fix":{"url":"https://github.com/statamic/cms/commit/e59dd342c83bc45de26573cfb0536a0bca98255a","label":"statamic/cms@e59dd34"},"references":[{"type":"WEB","url":"https://github.com/statamic/cms/releases/tag/v5.74.1"},{"type":"WEB","url":"https://github.com/statamic/cms/releases/tag/v6.24.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64665.json"},{"type":"ADVISORY","url":"https://github.com/statamic/cms/security/advisories/GHSA-93qh-5269-9wcf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64665"},{"type":"FIX","url":"https://github.com/statamic/cms/commit/e59dd342c83bc45de26573cfb0536a0bca98255a"},{"type":"FIX","url":"https://github.com/statamic/cms/pull/14887"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:31:02.321258892Z"}}
