Umbraco has a Management API Vulnerability to Path Traversal With Authenticated Users ### Impact Authenticated users to the Umbraco backoffice are able to craft management API request that exploit a path traversal vulnerability to upload files into a incorrect location. ### Patches The issue affects Umbraco 14+ and is patched in 14.3.4 and 15.3.1. ### Workarounds Umbraco supports the configuration of [allowed](https://docs.umbraco.com/umbraco-cms/reference/configuration/contentsettings#allowed-upload-file-extensions) and [disallowed file extensions](https://docs.umbraco.com/umbraco-cms/reference/configuration/contentsettings#disallowed-upload-file-extensions).
