## Technical details

Missing authorization checks on the GET /client/{clientId} and GET /client/export endpoints in SysClientController allow authenticated users without client-manage permissions to retrieve OAuth2 client secrets. An attacker with valid credentials can extract clientSecret values for seed clients and export the entire client table, then use those credentials to obtain tokens via the configured OAuth2 grant types.
