Description
yudao-cloud through 2026.09 contains an authorization bypass vulnerability that allows authenticated users to evade row-level data scope restrictions by sending a data-permission-enable header set to false. Attackers can add this header to /admin-api requests, which DataPermissionRpcWebFilter trusts, to read or modify other departments' and users' records within the same tenant.
