Authenticated attackers, including unprivileged Subscribers, can supply an arbitrary post_id for any course, lesson, or quiz to create a private message addressed to that post's author, bypassing the enrollment checks enforced by the newer REST send-message controller.","severity":"medium","score":5.3,"published":"2026-10-19T14:45:24.844Z","modified":"2026-10-27T10:14:04.227Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://senseilms.com/release-notes/","https://www.vulncheck.com/advisories/sensei-lms-broken-access-control-via-save-new-message"],"sources":[{"name":"CVE","id":"CVE-2026-112329","modified":"2026-10-27T10:14:04.227Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-112329"}],"assessments":[{"source":"VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.3},{"source":"VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T22:25:35.093Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
