Name of the Vulnerable Software and Affected Versions: Umbraco Forms versions 7.x through 13.4.1 Umbraco Forms versions 15.1.1 and earlier

Description: The issue affects Umbraco Forms, a form builder that integrates with the Umbraco content management system. It is related to the 'Send email' workflow, which does not HTML encode user-provided field values in the sent email message. This allows sending messages from a trusted system and address, potentially bypassing spam and email client security systems.

Recommendations: For Umbraco Forms versions 7.x through 13.4.1, update to version 13.4.2 or later. For Umbraco Forms versions 15.1.1 and earlier, update to version 15.1.2 or later. As a temporary workaround for unpatched or unsupported versions, consider using the Send email with template (Razor) workflow instead of the vulnerable 'Send email' workflow. To prevent accidental use of the vulnerable workflow, the SendEmail workflow type can be removed using a composer available in the GitHub Security Advisory for this issue.
