Prior to 1.11.38 and 2.0.0-RC.3, Chamilo LMS contains an Insecure Direct Object Reference (IDOR) vulnerability in the Learning Path progress saving endpoint. The file lp_ajax_save_item.php accepts a uid (user ID) parameter directly from $_REQUEST and uses it to load and modify another user's Learning Path progress — including score, status, completion, and time — without verifying that the requesting user matches the target user ID. Any authenticated user enrolled in a course can overwrite another user's Learning Path progress by simply changing the uid parameter in the request. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3."}],"source":{"advisory":"GHSA-3rv7-9fhx-j654","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-3rv7-9fhx-j654","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-13T15:28:28.539478Z","id":"CVE-2026-33702","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-13T15:36:13.742Z"}}]}}
