FKIE_CVE-2025-47280

Vulnerability from fkie_nvd - Published: 2025-05-13 17:16 - Updated: 2026-06-17 09:27
Severity
6.1 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Summary
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.

A partir de la rama 7.x y en versiones anteriores a la 13.4.2 y la 15.1.2, el flujo de trabajo \"Send email\" no codifica en HTML los valores de los campos proporcionados por el usuario en el correo electr\u00f3nico enviado, lo que hace vulnerable cualquier formulario con este flujo de trabajo configurado, ya que permite enviar el mensaje desde un sistema y una direcci\u00f3n de confianza, lo que podr\u00eda eludir los sistemas de seguridad de correo no deseado y de los clientes de correo electr\u00f3nico. Este problema afecta a todas las versiones compatibles de Umbraco Forms y est\u00e1 parcheado en las versiones 13.4.2 y 15.1.2. Las versiones sin parchear o sin soporte pueden solucionar este problema utilizando el flujo de trabajo \"Enviar correo electr\u00f3nico con plantilla (Razor)\" o creando un tipo de flujo de trabajo personalizado. Para evitar volver a utilizar accidentalmente el flujo de trabajo vulnerable, el tipo de flujo de trabajo \"Enviar correo electr\u00f3nico\" se puede eliminar mediante un editor disponible en el aviso de seguridad de GitHub para esta vulnerabilidad."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
