Can vary a lot from project to project. Usually there is a bottleneck where new code is certainly getting looked at before being merged, not that things can't go unnoticed. Depending on the size of the project, full audits can be performed by third parties. If it's popular enough or there are bug bounties up, random people might be looking for issues as well. In general, the less popular, the less likely it is someone has recently taken a look at the code.
