JeecgBoot through 3.9.5 contains a missing authorization vulnerability in SysAnnouncementSendController that allows authenticated users to modify other users' message delivery records. Attackers can obtain delivery ids from GET /sys/sysAnnouncementSend/list and submit edit requests that overwrite read flags, recipient ids, or linked announcements to hide messages from recipients.
