{"id":"CVE-2026-30881","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-30881","generatedAt":"2026-10-28T00:27:50.141Z","title":"Version 1.11.34 and prior contains a SQL Injection vulnerability in the statistics AJAX endpoint.","description":"Chamilo LMS is a learning management system. Version 1.11.34 and prior contains a SQL Injection vulnerability in the statistics AJAX endpoint. The parameters date_start and date_end from $_REQUEST are embedded directly into a raw SQL string without proper sanitization. Although Database::escape_string() is called downstream, its output is immediately neutralized by str_replace(\"\\'\", \"'\", ...), which restores any injected single quotes — effectively bypassing the escaping mechanism entirely. This allows an authenticated attacker to inject arbitrary SQL statements into the database query, enabling blind time-based and conditional data extraction. This issue has been patched in version 1.11.36.","published":"2026-03-16T20:16:19.000Z","lastModified":"2026-06-17T10:33:05.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-89"],"affected":["chamilo/chamilo lms"],"epss":{"score":0.00287,"percentile":0.21014,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.29%).
