CVE-2025-41103Network attack vector

Authenticated HTML injection via unvalidated reply_message

Published Nov 11, 2025 · Updated Nov 11, 2025

Stored HTML injection in Fairsketch RISE CRM Framework before 3.9 allows remote authenticated users to alter message-reply content. The /messages/reply handler accepts reply_message from a POST request without proper validation and incorporates the supplied HTML into a reply. Exploitation requires an authenticated account and a recipient who views the crafted reply, limiting the demonstrated impact to attacker-controlled content in that recipient's browser.
