Technical details

The SysRoleController saveDatarule handler lacks proper authorization validation, allowing authenticated attackers to send crafted permissionId, roleId, and dataRuleIds parameters to overwrite data_rule_ids for any role. This clears row-level security filters, bypassing data access controls. The vulnerability requires valid authentication but no elevated privileges to exploit.
