Authenticated code execution via untrusted WSDL compilation
Published Jan 16, 2026 · Updated Jan 16, 2026
Remote code execution in Umbraco Forms 8.13.16 and earlier allows remote authenticated users to execute code through a malicious WSDL URL. The Webservice data-source provider accepts an attacker-controlled URL and dynamically generates a SOAP client from the retrieved WSDL without restricting trusted sources. A backoffice account able to manage data sources is required, and successful exploitation runs attacker-supplied code in the server application context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
