Technical details

The SysMessageTemplateController delete handler lacks @RequiresPermissions authorization checks, allowing any authenticated user to invoke removeById() and physically delete rows from the sys_sms_template table. The vulnerability requires valid authentication but no specific role or permission; template IDs are enumerable via the unguarded list endpoint. An authenticated attacker gains the ability to disable system notification functionality by removing shipped templates.
