Description
Huginn before 2026.11.05 contains a stored cross-site scripting vulnerability in the service_label helper that marks unescaped OAuth service display names as html_safe. Authenticated attackers can connect an OAuth account with a crafted nickname, name or email and share it globally, executing JavaScript when victims attach it to Agents and view them, exposing Credentials, Agents and Events, and admin actions if the victim is an administrator.
