I was working Southwest flow; arrivals to satellite airports and multiple smaller uncontrolled airports. I vectored Aircraft X for an ILS 23 approach to MMU airport. I turned and cleared Aircraft X at 2000 ft for approach. This was the approach in use. I noticed a 1200 code climbing out of CDW airport NW bound leaving 1000 ft. I monitored this aircraft's climb and figured he would stop at 1500 ft. The aircraft continued to climb to 2000 ft directly in front of Aircraft X also at 2000 on localizer. I issued traffic to Aircraft X. Aircraft X got a TCAS alert and climbed above the traffic. He then descended back to localizer and glide slope. I asked if he would like to be vectored for the approach again; he said no that he would continue and land. I called CDW Tower about the VFR and they were speaking to the aircraft. I asked why they would let him climb directly in front of an aircraft on an instrument approach. I believe they said they thought he would stop below Aircraft X. This has been going on for years; VFR's off of this airport climb directly into IFR arrivals on the approach and cleared. This is so dangerous; and the Tower likes to say that the aircraft departing are VFR and they can do what they want. They are in their Class D and should not be allowed to climb directly into another aircraft just because they are VFR. I believe that a mid-air collision is going to happen if you continue to have aircraft climbing and descending to the same altitude. There is no separation between these aircraft. I reported this problem to my supervisor who said they would look into it. This situation has been report many times in house. This needs to stop now. An IFR on approach should not have to be looking for VFR's right in his face; at his altitude. This has to be looked into; no more games with pilots' lives. This airport's controllers should not allow these pilots to climb directly into another aircraft and say they're 'VFR.' I thought we were Air Traffic Controllers.
A TRACON Controller reported a VFR aircraft climbed into the path of an aircraft on an instrument approach to a nearby airport and that this is a recurring problem.
