{"id":"CVE-2026-45146","published":"2026-11-03T20:18:13.943","lastModified":"2026-11-03T20:18:13.943","description":"Chamilo LMS is an open-source learning management system. Prior to 1.11.40 and 2.0.1, an authenticated administrator can call the get_sessions action in /main/inc/ajax/model.ajax.php with _search=true and a crafted JSON filters parameter whose groupOp field contains SQL syntax. Because groupOp is not restricted to the expected AND or OR operators before it is incorporated into query logic, attacker-controlled input is interpreted by the database and enables blind or time-based SQL injection. Successful exploitation can disclose sensitive user, course, session, configuration, password-reset, and administrative data, modify or delete records subject to database privileges, and cause denial of service through expensive delayed queries. This issue is fixed in versions 1.11.40 and 2.0.1.","cvssScore":7.2,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-89"],"vendors":[],"products":[],"references":[{"url":"https://github.com/chamilo/chamilo-lms/commit/4472f3089bbbca1b4713bfd7059907676b80d07f","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/commit/7cc961d60ac27eaccd6bcc8db201de2c65adfdf3","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/releases/tag/v1.11.40","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/releases/tag/v2.0.1","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-prqp-8x29-cr88","tags":[]}],"exploitRefs":[{"url":"https://github.com/chamilo/chamilo-lms/commit/4472f3089bbbca1b4713bfd7059907676b80d07f","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/commit/7cc961d60ac27eaccd6bcc8db201de2c65adfdf3","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/releases/tag/v1.11.40","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/releases/tag/v2.0.1","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-prqp-8x29-cr88","tags":[]}],"hasPoc":true,"ai":null}
