A malicious user can call the vulnerable procedure of this package with specially crafted parameters and execute SQL statements with the elevated privileges of the SYS user. Any Oracle database user with EXECUTE privilege on the package SYS.DBMS_CDC_PUBLISH can exploit this vulnerability. By default, users granted EXECUTE_CATALOG_ROLE have the required privilege.
