If a malicious backup file is restored, it could lead to unintended execution of server-side code. Since restore capabilities are typically available to privileged users, exploitation requires authenticated access. Successful exploitation could result in full compromise of the Moodle server.","published":"2026-02-21T05:40:05.763Z","modified":"2026-08-12T03:51:18.456710789Z","cvss":{"score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00553,"percentile":0.44851,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"moodle/moodle","fixedVersion":"5.1.2"},{"ecosystem":"Packagist","name":"moodle/moodle","fixedVersion":"5.0.5"},{"ecosystem":"Packagist","name":"moodle/moodle","fixedVersion":"4.5.9"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-26045"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26045.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26045"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2440901"},{"type":"PACKAGE","url":"https://github.com/moodle/moodle"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:18.456710789Z"}}
