A user's CSRF token was unnecessarily included in the URL when being redirected to a course they have just restored. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website. This flaw allows an attacker to perform cross-site request forgery attacks.","published":"2022-11-23T00:00:00Z","modified":"2026-08-12T03:51:14.928375261Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"moodle/moodle","fixedVersion":"3.9.18"},{"ecosystem":"Packagist","name":"moodle/moodle","fixedVersion":"3.11.11"},{"ecosystem":"Packagist","name":"moodle/moodle","fixedVersion":"4.0.5"}],"fix":null,"references":[{"type":"WEB","url":"http://git.moodle.org/gw?p=moodle.git&a=search&h=HEAD&st=commit&s=MDL-75862"},{"type":"WEB","url":"https://moodle.org/mod/forum/discuss.php?d=440769"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/45xxx/CVE-2022-45149.json"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2DHYIIAUXUBHMBEDYU7TYNZXEN2W2SA2/"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/74SXNGA5RIWM7QNX7H3G7SYIQLP4UUGV/"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NLRJB5JNKK3VVBLV3NH3RI7COEDAXSAB/"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-45149"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2142772"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:14.928375261Z"}}
