Description
JeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows low-privileged authenticated users to modify message templates via PUT /sys/message/sysMessageTemplate/edit. Attackers can obtain template ids from the unguarded list endpoint and overwrite system notification titles and content, delivering attacker-supplied text or links to other users.
