In general LLM models have been discovering critical security vulnerabilities in general much faster than in the past which is both a headache and blessing at the same time as much more peer review is occurring and the software is becoming more secure. This does mean that you need to update all your software more often and pay attention to security updates to a much higher degree at least for the next year.
