From 2.0.0 through at least 2.1.0, Chamilo LMS stores private Message.content without server-side sanitization and renders it as HTML in assets/vue/views/message/MessageShow.vue and public/main/template/default/message/view_message.html.twig. An authenticated low-privilege user, including a student, can directly address crafted message content to an administrator because the message creation flow permits a sender to select another user as the recipient. The content executes in the recipient's browser when the recipient opens the routine inbox or message view, without requiring a link click, and can expose session credentials or permit actions as the administrator. This vulnerability is fixed in 2.0.1.","state":0,"publishedAt":"2026-09-17T20:09:57.972+00:00","modifiedAt":"2026-09-24T20:55:23.244+00:00","affected":[{"ecosystem":"Vendor product","name":"chamilo-lms","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"chamilo\",\n                    \"product\": \"chamilo-lms\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.0.0, < 2.0.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","score":9,"severity":"CRITICAL"}],"references":["https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-x88v-rg6r-vqq6","https://github.com/chamilo/chamilo-lms/commit/b2c91c021fc5ab7e91feb4927c4c676f77034ac5","https://github.com/chamilo/chamilo-lms/releases/tag/v2.0.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-45143","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-45143","identifiers":["CVE-2026-45143"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
