{"id":"CVE-2026-45145","published":"2026-10-30T15:16:51.923","lastModified":"2026-10-30T17:13:54.187","description":"Chamilo LMS is an open-source learning management system. Prior to 2.0.1, `public/main/inc/lib/career.lib.php` and `public/main/cron/import_csv.php` call PHP's native `unserialize()` on `user_career.extra_data` retrieved from the database without the `allowed_classes: false` safety option. An attacker able to write crafted serialized PHP objects to that column, for example through a separate SQL injection, a compromised admin CSV import, or a lower-privilege admin panel, can instantiate arbitrary PHP objects and trigger POP gadget chains in autoloaded `Symfony`, `Doctrine`, or `Monolog` components. This permits arbitrary OS commands as the web server user, compromising server confidentiality, integrity, and availability. This issue is fixed in version 2.0.1.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://github.com/chamilo/chamilo-lms/commit/4da33d8fd317fe5d58041f3202dddc62282ef2fb","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/releases/tag/v2.0.1","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-pr59-4rm7-ghwx","tags":[]}],"exploitRefs":[{"url":"https://github.com/chamilo/chamilo-lms/commit/4da33d8fd317fe5d58041f3202dddc62282ef2fb","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/releases/tag/v2.0.1","tags":[]},{"url":"https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-pr59-4rm7-ghwx","tags":[]}],"hasPoc":true,"ai":null}
