A vulnerability was identified in JeecgBoot up to 3.9.1. The impacted element is an unknown function of the file /sys/comment/add. Such manipulation leads to improper access controls. The attack can be executed remotely. The exploit is publicly available and might be used. Upgrading to version 3.9.2 is sufficient to resolve this issue. Upgrading the affected component is recommended.
