CVE-2023-48227: 
C# vulnerability analysis and mitigation

Umbraco, an ASP.NET content management system (CMS), disclosed a security vulnerability (CVE-2023-48227) affecting versions from 8.0.0 up to versions 8.18.10, 10.7.0, and 12.3.0. The vulnerability allows backoffice users with 'send for approval' permission but without publish permission to bypass restrictions and publish content in certain scenarios (GitHub Advisory).

The vulnerability stems from a permission bypass issue where users can modify the request body of the 'Send for Approval' request to gain unauthorized publishing capabilities. The vulnerability has been assigned a CVSS v3.1 base score of 4.3 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N, indicating it requires network access, low attack complexity, low privileges, and no user interaction (NVD).

The vulnerability allows unauthorized publishing of content by users who should only have 'send for approval' permissions. This could lead to premature or unauthorized content publication, potentially affecting the integrity of the content management workflow (GitHub Advisory).

The vulnerability has been patched in Umbraco versions 8.18.10, 10.7.0, and 12.3.0. Users are advised to upgrade to these or newer versions. No known workarounds are available for unpatched versions (NVD).
