Description
JeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows low-privileged authenticated users to create validation rules through the SysCheckRuleController importExcel handler. Attackers can upload a crafted Excel workbook to bypass the system:checkRule:add permission and bulk-create system-wide encoding validation rules with arbitrary regular expression patterns.
