CVE-2024-48925
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUmbraco, a free and open source .NET content management system, has an improper access control issue starting in version 14.0.0 and prior to version 14.3.0. The issue allows low-privilege users to access the webhook API and retrieve information that should be restricted to users with access to the settings section. Version 14.3.0 contains a patch.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceUmbraco CMS versions 14.0.0 through 14.2.x contain an improper access control vulnerability where low-privilege users can access webhook API endpoints that should be restricted to users with settings section permissions, allowing unauthorized retrieval of sensitive configuration information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Umbraco CMS installation and versionLocate the Umbraco installation and check the version file or DLL properties. Common paths include the website root directory. Look for version information in assembly metadata or a version.json file if present.Affected if Installed version is between 14.0.0 and 14.2.x inclusive
-
Confirm webhook feature is in useCheck if the Webhooks module is enabled in the Umbraco backoffice under the Settings section, or inspect the configuration files for webhook-related settings (such as appsettings.json for webhook configuration entries).Affected if Webhooks are enabled and configured in the environment
-
Review user permissions configurationExamine the Umbraco backoffice users section to identify which users are assigned to user groups with limited permissions (not containing settings section access). Check the Users section in the admin panel or inspect the database user/usergroup tables.Affected if There exist users with limited permissions who should not have access to settings section
-
Test webhook API endpoint accessUsing a low-privilege user account (without settings section permissions), attempt to access the webhook API endpoints directly via HTTP request to paths such as /umbraco/api/webhook/ or similar endpoint patterns under the API routes.Affected if The low-privilege user can successfully retrieve webhook configuration data via API without authorization error
A user is affected if their Umbraco CMS version falls within 14.0.0 to 14.2.x, the webhook feature is enabled, and low-privilege users can access webhook API endpoints without proper authorization checks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped14.3.0
Upgrade Umbraco to version 14.3.0 or later which contains the patch for this authorization bypass vulnerability.
14.3.0
- Back up the existing Umbraco CMS database and files
- Ensure the production environment is not directly accessible during upgrade
- Consult Umbraco upgrade documentation for version-specific migration notes
- Upgrade Umbraco CMS from any version >= 14.0.0 and < 14.3.0 to version 14.3.0
- Verify the upgrade was successful by checking the admin interface
- Test that low-privilege users can no longer access webhook API endpoints
