{"id":"BIT-moodle-2026-26045","summary":"Moodle: moodle: improper validation in file restore functionality leading to remote code execution","details":"A flaw was identified in Moodle’s backup restore functionality where specially crafted backup files were not properly validated during processing. 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.","aliases":["CVE-2026-26045","GHSA-ggxq-2mg9-8966"],"modified":"2026-09-08T08:48:15.542586957Z","published":"2026-03-02T08:50:23.910Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:moodle:moodle:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-26045"},{"type":"ADVISORY","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2440901"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26045"}],"affected":[{"package":{"name":"moodle","ecosystem":"Bitnami","purl":"pkg:bitnami/moodle"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.5.9"},{"introduced":"5.0.0"},{"fixed":"5.0.5"},{"introduced":"5.1.0"},{"fixed":"5.1.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/moodle/BIT-moodle-2026-26045.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.9.0"}
