You'll have to *alias* your columns, not prefix it with the table names:
$[CHE_TEST@asterix1_impl] r
  1  declare
  2    cursor cData is
  3      with data as (
  4        select 1 id, 'test1' val1, 'a' val2 from dual
  5        union all
  6        select 1 id, '1test' val1, 'b' val2 from dual
  7        union all
  8        select 2 id, 'test2' val1, 'a' val2 from dual
  9        union all
10        select 2 id, '2test' val1, 'b' val2 from dual
11      )
12      select a.id, b.id, a.val1, b.val1, a.val2, b.val2
13      from data a, data b
14      where a.id = b.id
15      and a.val2 = 'a'
16      and b.val2 = 'b';
17  begin
18    for rData in cData loop
19      null;
20    end loop;
21* end;
  for rData in cData loop
