Threats affecting pkg:github/umbraco/Umbraco-CMS

Umbraco CMS versions prior to 13.14.0 and 17.4.0 contain an open redirect vulnerability in some Surface Controllers that handle member-related operations. These controllers fail to properly validate redirect URLs derived from user-controlled query parameters, allowing malicious redirection. This vulnerability has been addressed in versions 13.14.0 and 17.4.0.

Umbraco is an ASP.NET content management system (CMS). Starting in version 14.0.0 and prior to versions 15.4.2 and 16.0.0, it's possible to upload a file that doesn't adhere with the configured allowable file extensions via a manipulated API request. The issue is patched in versions 15.4.2 and 16.0.0. No known workarounds are available.
