Live › vulnerability › CVE-2026-45145
Chamilo LMS calls PHP's unserialize() on database content without restricting object classes, so crafted serialized objects can be instantiated. An attacker who can write to that column can chain gadgets in bundled Symfony, Doctrine, or Monolog components to run OS commands as the web server user.

Organisations running self-hosted Chamilo LMS before 2.0.1 where the career or CSV import features store data in user_career.extra_data. Exposure depends on an attacker being able to write to that column, through SQL injection, a compromised admin CSV import, or a lower-privilege admin account. Managed hosting handled by the vendor and instances already on 2.0.1 or later are not affected.
No product ranges from the sources yet.
2.0.1.unserialize( calls without allowed_classes in public/main/inc/lib/career.lib.php and public/main/cron/import_csv.php.2.0.1 or later.Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
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.
