I'd say absent some temporary hack to do something, my bad experiences won't let me say something is low risk. I worked at Microsoft years ago, and after the zillions of vulnerabilities were attacked by people around the time of windows 95 and computers on the net, we did serious code reviews in my team of the data access libraries. There were vast numbers of vulnerabilities. A group of 3 or 4 of us would sit in a room for 3 hours a day, one person a scribe, and we'd go over this c code that was ancient even then - we found problems everywhere, it was exhausting and shocking. The entire data access infrastructure was riddled with memory leaks, strings that were not length limited, input parameters that were not checked or sanitized, etc. I'm sure it was endemic across all components, not just there. We fixed some things, but we found so much shit.
Thank got I wasn't on the team trying to figure out what to do about those problems. I think they end of lifed a lot of stuff.
