{"id":"CVE-2021-33898","details":"In Invoice Ninja before 4.4.0, there is an unsafe call to unserialize() in app/Ninja/Repositories/AccountRepository.php that may allow an attacker to deserialize arbitrary PHP classes. In certain contexts, this can result in remote code execution. The attacker's input must be hosted at http://www.geoplugin.net (cleartext HTTP), and thus a successful attack requires spoofing that site or obtaining control of it.","modified":"2025-11-20T11:47:25.316020Z","published":"2021-06-06T23:15:07.517Z","references":[{"type":"FIX","url":"https://github.com/invoiceninja/invoiceninja/issues/5909"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/invoiceninja/invoiceninja","events":[{"introduced":"0"},{"fixed":"4cda561fae1a10a970b1c4251a2962ed77ccc81c"}]}],"versions":["v1.0.2","v1.0.3","v1.1.0","v1.1.1","v1.1.2","v1.2.0","v1.2.1","v1.2.2","v1.3.0","v1.3.1","v1.3.2","v1.3.3","v1.4.0","v1.5.0","v1.5.1","v1.5.2","v1.6.0","v1.6.1","v1.7.0","v1.7.1","v1.7.2","v2.0.0","v2.0.0_RC1","v2.0.1","v2.1.0","v2.1.1","v2.1.2","v2.2.0","v2.2.1","v2.2.2","v2.3.0","v2.3.1","v2.3.2","v2.3.3","v2.3.4","v2.4.0","v2.4.1","v2.4.2","v2.4.3","v2.4.4","v2.4.5","v2.4.6","v2.4.7","v2.4.8","v2.4.8.1","v2.4.9","v2.4.9.1","v2.4.9.2","v2.4.9.3","v2.4.9.4","v2.4.9.5","v2.4.9.6","v2.5.0","v2.5.0.1","v2.5.0.2","v2.5.0.3","v2.5.0.4","v2.5.1","v2.5.1.1","v2.5.1.2","v2.5.1.3","v2.5.2","v2.5.2.1","v2.5.2.2","v2.6","v2.6.1","v2.6.10","v2.6.11","v2.6.2","v2.6.3","v2.6.4","v2.6.5","v2.6.6","v2.6.7","v2.6.8","v2.6.9","v2.7","v2.7.1","v2.7.2","v2.8","v2.8.1","v2.8.2","v2.9.0","v2.9.1","v2.9.2","v2.9.3","v2.9.4","v2.9.5","v3.0.0","v3.0.1","v3.0.2","v3.0.3","v3.0.4","v3.0.5","v3.1.0","v3.1.1","v3.1.2","v3.1.3","v3.2.0","v3.2.1","v3.3.0","v3.3.1","v3.3.3","v3.4.0","v3.4.1","v3.4.2","v3.5.0","v3.5.1","v3.6.0","v3.6.1","v3.7.0","v3.7.1","v3.7.2","v3.8.0","v3.8.1","v3.9.0","v3.9.1","v3.9.2","v4.0.0","v4.0.1","v4.1.0","v4.1.1","v4.1.2","v4.1.3","v4.1.4","v4.1.5","v4.2.0","v4.2.1","v4.2.2","v4.3.0","v4.3.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-33898.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
