Mozilla shifted away from patching individual Firefox sandbox escape and JavaScript prototype vulnerabilities. Instead, they implemented an architectural change by freezing JavaScript prototypes. This move reduced entire classes of exploit paths rather than addressing each vulnerability individually. It highlights a fundamental security tradeoff: patching treats symptoms, while architectural changes address root causes. Many teams still prioritize vulnerability volume metrics over systemic design improvements, which can lead to reactive rather than preventive security postures. Should modern security programs prioritize reducing CVEs — or eliminating entire categories of vulnerabilities through design?
