| CVE-2026-31832 | 1 Umbraco | 1 Umbraco Cms | 2026-03-18 | N/A | 5.4 MEDIUM |
| Umbraco is an ASP.NET CMS. From 14.0.0 to before 16.5.1 and 17.2.2, A broken object-level authorization vulnerability exists in a backoffice API endpoint that allows authenticated users to assign domain-related data to content nodes without proper authorization checks. The issue is caused by insufficient authorization enforcement on the affected API endpoint, whereby via an API call, domains can be set on content nodes that the editor does not have permission to access (either via user group privileges or start nodes). This vulnerability is fixed in 16.5.1 and 17.2.2. | |||||
| CVE-2026-31833 | 1 Umbraco | 1 Umbraco Cms | 2026-03-18 | N/A | 6.7 MEDIUM |
| Umbraco is an ASP.NET CMS. From 16.2.0 to before 16.5.1 and 17.2.2, An authenticated backoffice user with access to Settings can inject malicious HTML into property type descriptions. Due to an overly permissive attributeNameCheck configuration (/.+/) in the UFM DOMPurify instance, event handler attributes such as onclick and onload, when used within Umbraco web components (umb-*, uui-*, ufm-*) were not filtered. This vulnerability is fixed in 16.5.1 and 17.2.2. | |||||
| CVE-2026-31834 | 1 Umbraco | 1 Umbraco Cms | 2026-03-18 | N/A | 7.2 HIGH |
| Umbraco is an ASP.NET CMS. From 15.3.1 to before 16.5.1 and 17.2.2, A privilege escalation vulnerability has been identified in Umbraco CMS. Under certain conditions, authenticated backoffice users with permission to manage users, may be able to elevate their privileges due to insufficient authorization enforcement when modifying user group memberships. The affected functionality does not properly validate whether a user has sufficient privileges to assign highly privileged roles. This vulnerability is fixed in 16.5.1 and 17.2.2. | |||||
| CVE-2026-24687 | 3 Apple, Linux, Umbraco | 3 Macos, Linux Kernel, Umbraco Forms | 2026-03-02 | N/A | 6.5 MEDIUM |
| Umbraco Forms is a form builder that integrates with the Umbraco content management system. 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. This issue affects versions 16 and 17 of Umbraco Forms and is patched in 16.4.1 and 17.1.1. 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, and/or 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. | |||||
| CVE-2025-68924 | 1 Umbraco | 1 Umbraco Forms | 2026-02-20 | N/A | 7.5 HIGH |
| In Umbraco UmbracoForms through 8.13.16, an authenticated attacker can supply a malicious WSDL (aka Webservice) URL as a data source for remote code execution. | |||||
| CVE-2021-47776 | 1 Umbraco | 1 Umbraco Cms | 2026-01-23 | N/A | 5.3 MEDIUM |
| 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. Attackers can craft malicious requests to the GetContextHelpForPage, GetRemoteDashboardContent, and GetRemoteDashboardCss endpoints to trigger unauthorized server-side requests to external hosts. | |||||
| CVE-2025-67288 | 1 Umbraco | 1 Umbraco Cms | 2026-01-08 | N/A | 10.0 CRITICAL |
| An arbitrary file upload vulnerability in Umbraco CMS v16.3.3 allows attackers to execute arbitrary code by uploading a crafted PDF file. NOTE: this is disputed by the Supplier because the responsibility for file validation (as shown in the documentation) belongs to the system administrator who is implementing Umbraco CMS in their environment, not to Umbraco CMS itself, a related issue to CVE-2023-49279. | |||||
| CVE-2024-35239 | 1 Umbraco | 1 Umbraco Forms | 2026-01-05 | N/A | 2.7 LOW |
| Umbraco Commerce is an open source dotnet web forms solution. In affected versions an authenticated user that has access to edit Forms may inject unsafe code into Forms components. This issue can be mitigated by configuring TitleAndDescription:AllowUnsafeHtmlRendering after upgrading to one of the patched versions (13.0.1, 12.2.2, 10.5.3, 8.13.13). | |||||
| CVE-2025-66625 | 1 Umbraco | 1 Umbraco Cms | 2026-01-02 | N/A | 4.9 MEDIUM |
| Umbraco is an ASP.NET CMS. Due to unsafe handling and deletion of temporary files in versions 10.0.0 through 13.12.0, during the dictionary upload process an attacker with access to the backoffice can trigger predictable requests to temporary file paths. The application’s error responses (HTTP 500 when a file exists, 404 when it does not) allow the attacker to enumerate the existence of arbitrary files on the server’s filesystem. This vulnerability does not allow reading or writing file contents. In certain configurations, incomplete clean-up of temporary upload files may additionally expose the NTLM hash of the Windows account running the Umbraco application. This issue is fixed in version 13.12.1. | |||||
| CVE-2024-55488 | 1 Umbraco | 1 Umbraco Cms | 2025-12-31 | N/A | 6.5 MEDIUM |
| A stored cross-site scripting (XSS) vulnerability in Umbraco CMS v14.3.1 allows attackers to execute arbitrary web scripts or HTML via a crafted payload. NOTE: This has been disputed by the vendor since this potential attack is only possible via authenticated users who have been manually allowed access to the CMS. There was a deliberate decision made not to apply HTML sanitization at the product level. | |||||
| CVE-2025-27601 | 1 Umbraco | 1 Umbraco Cms | 2025-09-22 | N/A | 4.3 MEDIUM |
| Umbraco is a free and open source .NET content management system. An improper API access control issue has been identified Umbraco's API management package prior to versions 15.2.3 and 14.3.3, allowing low-privilege, authenticated users to create and update data type information that should be restricted to users with access to the settings section. The issue is patched in versions 15.2.3 and 14.3.3. No known workarounds are available. | |||||
| CVE-2025-27602 | 1 Umbraco | 1 Umbraco Cms | 2025-09-22 | N/A | 4.9 MEDIUM |
| Umbraco is a free and open source .NET content management system. In versions of Umbraco's web backoffice program prior to versions 10.8.9 and 13.7.1, via manipulation of backoffice API URLs, it's possible for authenticated backoffice users to retrieve or delete content or media held within folders the editor does not have access to. The issue is patched in versions 10.8.9 and 13.7.1. No known workarounds are available. | |||||
| CVE-2025-32017 | 1 Umbraco | 1 Umbraco Cms | 2025-09-22 | N/A | 8.8 HIGH |
| Umbraco is a free and open source .NET content management system. 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. The issue affects Umbraco 14+ and is patched in 14.3.4 and 15.3.1. | |||||
| CVE-2025-48953 | 1 Umbraco | 1 Umbraco Cms | 2025-09-22 | N/A | 5.5 MEDIUM |
| 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. | |||||
| CVE-2025-49147 | 1 Umbraco | 1 Umbraco Cms | 2025-09-22 | N/A | 5.3 MEDIUM |
| Umbraco, a free and open source .NET content management system, has a vulnerability in versions 10.0.0 through 10.8.10 and 13.0.0 through 13.9.1. Via a request to an anonymously authenticated endpoint it's possible to retrieve information about the configured password requirements. The information available is limited but would perhaps give some additional detail useful for someone attempting to brute force derive a user's password. This information was not exposed in Umbraco 7 or 8, nor in 14 or higher versions. The vulnerability is patched in versions 10.8.11 and 13.9.2. | |||||
| CVE-2025-54425 | 1 Umbraco | 1 Umbraco Cms | 2025-09-22 | N/A | 5.3 MEDIUM |
| Umbraco is an ASP.NET CMS. In versions 13.0.0 through 13.9.2, 15.0.0 through 15.4.1 and 16.0.0 through 16.1.0, the content delivery API can be restricted from public access where an API key must be provided in a header to authorize the request. It's also possible to configure output caching, such that the delivery API outputs will be cached for a period of time, improving performance. There's an issue when these two things are used together, where caching doesn't vary by the header that contains the API key. As such, it's possible for a user without a valid API key to retrieve a response for a given path and query if it has recently been requested and cached by request with a valid key. This is fixed in versions 13.9.3, 15.4.4 and 16.1.1. | |||||
| CVE-2025-23041 | 1 Umbraco | 1 Umbraco Forms | 2025-09-19 | N/A | 5.8 MEDIUM |
| Umbraco.Forms is a web form framework written for the nuget ecosystem. Character limits configured by editors for short and long answer fields are validated only client-side, not server-side. This issue has been patched in versions 8.13.16, 10.5.7, 13.2.2, and 14.1.2. Users are advised to upgrade. There are no known workarounds for this issue. | |||||
| CVE-2012-10054 | 1 Umbraco | 1 Umbraco Cms | 2025-09-19 | N/A | 9.8 CRITICAL |
| Umbraco CMS versions prior to 4.7.1 are vulnerable to unauthenticated remote code execution via the codeEditorSave.asmx SOAP endpoint, which exposes a SaveDLRScript operation that permits arbitrary file uploads without authentication. By exploiting a path traversal flaw in the fileName parameter, attackers can write malicious ASPX scripts directly into the web-accessible /umbraco/ directory and execute them remotely. | |||||
| CVE-2025-46736 | 1 Umbraco | 1 Umbraco Cms | 2025-09-03 | N/A | 5.3 MEDIUM |
| Umbraco is a free and open source .NET content management system. Prior to versions 10.8.10 and 13.8.1, based on an analysis of the timing of post login API responses, it's possible to determine whether an account exists. The issue is patched in versions 10.8.10 and 13.8.1. No known workarounds are available. | |||||
| CVE-2025-47280 | 1 Umbraco | 1 Umbraco Forms | 2025-05-22 | N/A | 6.1 MEDIUM |
| Umbraco Forms is a form builder that integrates with the Umbraco content management system. Starting in the 7.x branch and prior to versions 13.4.2 and 15.1.2, the 'Send email' workflow does not HTML encode the user-provided field values in the sent email message, making any form with this workflow configured vulnerable, as it allows sending the message from a trusted system and address, potentially bypassing spam and email client security systems. This issue affects all (supported) versions Umbraco Forms and is patched in 13.4.2 and 15.1.2. Unpatched or unsupported versions can workaround this issue by using the `Send email with template (Razor)` workflow instead or writing a custom workflow type. To avoid accidentally using the vulnerable workflow again, the `SendEmail` workflow type can be removed using a composer available in the GitHub Security Advisory for this vulnerability. | |||||
