{"id":"CVE-2025-47280","aliases":[],"url":"https://o3.security/vulnerability/CVE-2025-47280","summary":"Umbraco.Forms has HTML injection vulnerability in 'Send email' workflow","details":"### Impact\nThe '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).\n\n### Patches\nThis issue affects all (supported) versions Umbraco Forms and is patched in 13.4.2 and 15.1.2.\n\n### Workarounds\nUnpatched or unsupported versions can workaround this issue by using the 'Send email with template (Razor)' workflow instead or [writing a custom workflow type](https://docs.umbraco.com/umbraco-forms/developer/extending/adding-a-workflowtype).\n\nTo avoid accidentally using the vulnerable workflow again, the `SendEmail` workflow type can be removed using the following composer (tested on Umbraco 10, 13, 14 and 15):\n```c#\nusing Umbraco.Cms.Core.Composing;\nusing Umbraco.Forms.Core.Providers.Extensions;\nusing Umbraco.Forms.Core.Providers.WorkflowTypes;\n\ninternal sealed class RemoveFormsSendEmailWorkflowTypeComposer : IComposer\n{\n    public void Compose(IUmbracoBuilder builder)\n        => builder.FormsWorkflows().Exclude<SendEmail>();\n}\n```","published":"2025-05-13T20:17:36Z","modified":"2025-05-13T20:43:21.071435Z","cvss":{"score":0,"severity":"NONE","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"NuGet","name":"Umbraco.Forms","fixedVersion":"13.4.2"},{"ecosystem":"NuGet","name":"UmbracoForms","fixedVersion":null},{"ecosystem":"NuGet","name":"Umbraco.Forms","fixedVersion":"15.1.2"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/umbraco/Umbraco.Forms.Issues/security/advisories/GHSA-2qrj-g9hq-chph"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-47280"},{"type":"PACKAGE","url":"https://github.com/umbraco/Umbraco.Forms.Issues"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2025-05-13T20:43:21.071435Z"}}
