AGMP Partners The Current State of Zero-Day Vulnerability Trends in Late 2025 Diving into the zero-day landscape as of mid-2026, it's clear the game has fundamentally shifted since even a year or two ago. We're seeing an acceleration in commoditization and a broadening of the attack surface that's frankly unnerving. The traditional "discovery to patch" cycle, already under immense pressure, is now often an afterthought for sophisticated actors who leverage these vulnerabilities for initial access and persistence within minutes of disclosure, sometimes even pre-disclosure. The exploit market, both legitimate and illicit, continues to mature, driving this velocity. What I've observed in our incident response engagements is that the average time between a zero-day being actively exploited in the wild and vendors issuing an advisory, let alone a patch, is shrinking. This puts immense pressur
