CVE-2026-45145

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/importcsv.php call PHP's native unserialize() on usercareer.extradata retrieved from the database without the allowedclasses: 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.
