{"id":"CVE-2018-19789","aliases":["GHSA-x3cf-w64x-4cp2"],"url":"https://o3.security/vulnerability/CVE-2018-19789","summary":"Symfony Path Disclosure","details":"An issue was discovered in Symfony 2.7.x before 2.7.50, 2.8.x before 2.8.49, 3.x before 3.4.20, 4.0.x before 4.0.15, 4.1.x before 4.1.9, and 4.2.x before 4.2.1. When using the scalar type hint `string` in a setter method (e.g. `setName(string $name)`) of a class that's the `data_class` of a form, and when a file upload is submitted to the corresponding field instead of a normal text input, then `UploadedFile::__toString()` is called which will then return and disclose the path of the uploaded file. If combined with a local file inclusion issue in certain circumstances this could escalate it to a Remote Code Execution.","published":"2018-12-18T22:29:04.947Z","modified":"2026-08-07T11:48:11.971081027Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"2.7.50"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"2.8.49"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"3.4.20"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"4.0.15"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"4.1.9"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"4.2.1"},{"ecosystem":"Packagist","name":"symfony/form","fixedVersion":"2.7.50"},{"ecosystem":"Packagist","name":"symfony/form","fixedVersion":"2.8.49"},{"ecosystem":"Packagist","name":"symfony/form","fixedVersion":"3.4.20"},{"ecosystem":"Packagist","name":"symfony/form","fixedVersion":"4.0.15"},{"ecosystem":"Packagist","name":"symfony/form","fixedVersion":"4.1.9"},{"ecosystem":"Packagist","name":"symfony/form","fixedVersion":"4.2.1"}],"fix":null,"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4TD3E7FZIXLVFG3SMFJPDEKPZ26TJOW7/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JZMRJ7VTHCY5AZK24G4QGX36RLUDTDKE/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OA4WVFN5FYPIXAPLWZI6N425JHHDSWAZ/"},{"type":"WEB","url":"https://seclists.org/bugtraq/2019/May/21"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/106249"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/03/msg00009.html"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4441"},{"type":"FIX","url":"https://symfony.com/blog/cve-2018-19789-disclosure-of-uploaded-files-full-path"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:48:11.971081027Z"}}
