CVE-2026-45145
Chamilo LMS: Database-backed PHP object injection in career deserialization
CVE-2026-45145 is a high vulnerability (CVSS 7.5) in Chamilo Chamilo-lms, published October 30, 2026. No source lists public exploit code. EPSS puts the chance of exploitation in the next 30 days at 0.35%, the 29th percentile. No source names a fixed version.
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.
