Umbraco.Forms has Path Traversal and File Enumeration Vulnerabilities in Linux/Mac

發布日:2026/1/30修改日:2026/2/3

描述

### Impact It's possible for an authenticated backoffice-user to enumerate and traverse paths/files on the systems filesystem and read their contents, on Mac/Linux Umbraco installations using Forms. As Umbraco Cloud runs in a Windows environment, Cloud users aren't affected. ### Patches This issue affects versions 16 and 17 of Umbraco Forms and is patched in 16.4.1 and 17.1.1 ### Workarounds If upgrading is not immediately possible, users can mitigate this vulnerability by: * Configuring a WAF or reverse proxy to block requests containing path traversal sequences (`../`, `..\`) in the `fileName` parameter of the export endpoint * Restricting network access to the Umbraco backoffice to trusted IP ranges * Blocking the `/umbraco/forms/api/v1/export` endpoint entirely if the export feature is not required However, upgrading to the patched version is strongly recommended. ### References Credit to Kevin Joensen from Baldur Security for finding this vulnerability
