{"id":"CVE-2019-16409","aliases":["GHSA-xm6j-x342-gwq9"],"url":"https://o3.security/vulnerability/CVE-2019-16409","summary":"SilverStripe Versioned Files module Unpublished files are exposed publicly","details":"In the Versioned Files module through 2.0.3 for SilverStripe 3.x, unpublished versions of files are publicly exposed to anyone who can guess their URL. This guess could be highly informed by a basic understanding of the symbiote/silverstripe-versionedfiles source code. (Users who upgrade from SilverStripe 3.x to 4.x and had Versioned Files installed have no further need for this module, because the 4.x release has built-in versioning. However, nothing in the upgrade process automates the destruction of these insecure artefacts, nor alerts the user to the criticality of destruction.)","published":"2019-09-26T16:15:11.267Z","modified":"2026-08-07T14:52:50.258394Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Packagist","name":"symbiote/silverstripe-versionedfiles","fixedVersion":null},{"ecosystem":"Packagist","name":"silverstripe/framework","fixedVersion":"4.3.5"},{"ecosystem":"Packagist","name":"silverstripe/framework","fixedVersion":"4.4.4"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://www.silverstripe.org/download/security-releases/cve-2019-16409"},{"type":"PACKAGE","url":"https://github.com/silverstripe/silverstripe-framework"},{"type":"PACKAGE","url":"https://github.com/symbiote/silverstripe-versionedfiles"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T14:52:50.258394Z"}}
