JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the sendBusAnnouncement handler of SystemApiController that allows any authenticated user to send announcements without the required permissions. Low-privileged attackers can POST crafted bodies to /sys/api/sendBusAnnouncement with forged sender, recipients, title and content to deliver spoofed admin or system messages for phishing.
