Executive summary: A 1Password / Off-by-1 Labs study evaluated 6,080 LLM-generated patches for recently disclosed CVEs and found that large language models often produce fixes that appear correct but leave exploitable paths, introduce new vulnerabilities, or break intended behavior; the work shows that correct guidance and human expert review are essential because flawed automated patches can be as costly as writing a correct patch manually.
