CVE-2026-108627

JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the loadDatarule handler of SysRoleController that lets any authenticated user query role data rules. Low-privileged attackers can request GET /sys/role/datarule/{permissionId}/{roleId} to read rule names, columns, conditions, values and bound rule ids for any role.
