CVE-2026-108887
JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysCommentController exportXls handler that allows any authenticated user to export all comments.
Does this matter?
Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.
Description

Low-privileged attackers can request /sys/comment/exportXls to download every sys_comment row, including comment text and user ids on records they cannot access.
