A stored cross-site scripting (XSS) vulnerability exists in Sangoma Switchvox SMB Edition 8.3 (104997) within the voicemail notification template functionality. The submit_modify_voicemail_template endpoint fails to properly sanitize HTML content supplied by authenticated users, allowing malicious JavaScript supplied through the template_text parameter to be stored server-side and subsequently rendered to other users.
