CVE-2025-47280: Umbraco.Forms has HTML injection vulnerability in 'Send email' workflow

May 13, 2025

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).
