{"id":"CVE-2026-45145","state":"PUBLISHED","title":"Chamilo LMS: Database-backed PHP object injection in career deserialization","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.","publishedAt":"2026-10-30T14:29:05.283Z","updatedAt":"2026-10-30T15:51:30.372Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["chamilo chamilo-lms"],"affected":[{"vendor":"chamilo","product":"chamilo-lms","versions":[{"version":"< 2.0.1","status":"affected"}]}],"references":["https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-pr59-4rm7-ghwx","https://github.com/chamilo/chamilo-lms/commit/4da33d8fd317fe5d58041f3202dddc62282ef2fb","https://github.com/chamilo/chamilo-lms/releases/tag/v2.0.1"],"weaknesses":["CWE-502"],"ingestedAt":"2026-10-30T15:58:06.618Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/45xxx/CVE-2026-45145.json","commit":"2b1b837cd89354d9c9a57d56e0640dc825b19235","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-45145","state":"PUBLISHED","datePublished":"2026-10-30T14:29:05.283Z","dateUpdated":"2026-10-30T15:51:30.372Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-08T20:44:38.963Z"},"containers":{"cna":{"title":"Chamilo LMS: Database-backed PHP object injection in career deserialization","descriptions":[{"lang":"en","value":"Chamilo LMS is an open-source learning management system.
