Umbraco Cms

Privilege escalation in Umbraco CMS versions 15.3.1 through 16.5.0 and 17.x before 17.2.2 allows authenticated backoffice users with user management permissions to assign themselves elevated privileges by bypassing authorization checks on role assignments. An attacker with these permissions could gain administrative access to the CMS without proper privilege validation. No patch is currently available for affected installations.

Umbraco is an ASP.NET CMS. From 16.2.0 to versions up to 16.5.1 is affected by cross-site scripting (xss) (CVSS 6.7).

Umbraco CMS versions 14.0.0 through 16.5.0 and 17.0.0-17.2.1 contain an authorization bypass in a backoffice API endpoint that allows authenticated editors to assign domain configurations to content nodes they lack permission to access. An attacker with valid credentials could exploit this to modify domain settings on restricted content, potentially affecting content visibility or routing. The vulnerability affects Umbraco deployments without patches 16.5.1 or 17.2.2 applied.

Umbraco CMS v8.14.1 contains a server-side request forgery vulnerability that allows attackers to manipulate baseUrl parameters in multiple dashboard and help controller endpoints. [CVSS 5.3 MEDIUM]

Arbitrary code execution in Umbraco CMS 16.3.3 is claimed via upload of a crafted PDF file that abuses insufficient file-type validation (CWE-434), potentially leading to server-side code execution. The finding is explicitly DISPUTED by Umbraco, which states that enforcing upload validation is the deploying administrator's responsibility per documentation, mirroring the earlier CVE-2023-49279. No public exploit is confirmed and EPSS is low (0.50%, 39th percentile), so despite the nominal CVSS 10.0 this reflects a contested, configuration-dependent condition rather than a proven turnkey RCE.
