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.","state":0,"publishedAt":"2026-10-19T14:45:24.844+00:00","modifiedAt":"2026-10-22T02:58:48.591+00:00","affected":[{"ecosystem":"Vendor product","name":"Sensei LMS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"Automattic\",\n                    \"product\": \"Sensei LMS\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"4.26.4\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3,"severity":"MEDIUM"}],"references":["https://senseilms.com/release-notes/","https://www.vulncheck.com/advisories/sensei-lms-broken-access-control-via-save-new-message"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112329","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112329","identifiers":["CVE-2026-112329"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
