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2.0.1.","score":7.5,"severity":"high","published":"2026-10-30T14:29:05.283Z","modified":"2026-10-30T15:51:30.372Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"chamilo","name":"chamilo-lms","platforms":[],"versions":[{"version":"< 2.0.1","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-45145"}],"remediation":[],"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"],"sources":[{"name":"CVE","id":"CVE-2026-45145","modified":"2026-10-30T15:51:30.372Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-45145"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.5}],"sourceAffected":[],"observedAt":"2026-10-30T16:16:36.389Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T10:20:31.211Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-30T16:20:35.285Z","attemptedAt":"2026-10-30T16:20:35.285Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-10-30T16:20:36.043Z","attemptedAt":"2026-10-30T16:20:36.043Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-30T16:20:35.934Z","attemptedAt":"2026-10-30T16:20:35.934Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-10-30T16:20:35.890Z","attemptedAt":"2026-10-30T16:20:35.890Z"}],"evidence":[{"source":"NVD","id":"CVE-2026-45145","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45145","modified":"2026-10-30T16:17:56.170","score":7.5,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","checkedAt":"2026-10-30T16:20:35.285Z"},{"source":"ENISA EUVD","id":"EUVD-2026-113997","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-113997","modified":"Oct 30, 2026, 2:29:05 PM","score":7.5,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","checkedAt":"2026-10-30T16:20:35.934Z"}],"aiSummary":null}
