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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7.2,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793735686162,"publishedAt":1793735686162,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-prqp-8x29-cr88"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/chamilo/chamilo-lms/commit/4472f3089bbbca1b4713bfd7059907676b80d07f"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/chamilo/chamilo-lms/commit/7cc961d60ac27eaccd6bcc8db201de2c65adfdf3"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/chamilo/chamilo-lms/releases/tag/v1.11.40"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/chamilo/chamilo-lms/releases/tag/v2.0.1"}],"remediation":[],"revision":"059e54a893b75ae1232c9b706ba06e056fac82636f55c98cb133c7b4f51d8ffd","sources":[{"modifiedAt":1793735686162,"name":"CNA: GitHub_M","retrievedAt":1793736576809,"url":"https://www.cve.org/CVERecord?id=CVE-2026-45146"}],"ssvc":null,"status":"published","title":"Chamilo LMS: Blind SQL Injection in model.ajax.php via filters[groupOp] authentificated","updatedAt":1793736576809}
