Worcester gave Leeds a late scare in the 70th minute with a converted try by Alex Grove and could have stolen the result with a Matthew Jones penalty or his drop goal attempt in the final five minutes.
The hosts opened up a 12-point gap in the first 25 minutes as Ceiron Thomas slotted four penalties.
Willie Walker put the Warriors' first points on the board five minutes before the break as the score was 12-3 at half-time.
