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.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://senseilms.com/release-notes/","tags":[]},{"url":"https://www.vulncheck.com/advisories/sensei-lms-broken-access-control-via-save-new-message","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
