The Current State of Zero-Day Vulnerability Trends in Late 2025 It's July 9, 2026, and the landscape for zero-day vulnerabilities has evolved significantly even since our last deep-dive discussion at the AGMP Partners’ internal threat intelligence seminar in Q4 2025. The exploit market has become less fragmented, coalescing around a few dominant brokers and nation-state buyers. We’re seeing a persistent, aggressive focus on supply chain vectors, specifically targeting CI/CD pipelines, container registries, and software distribution channels. The solarwinds and log4j fallouts were not isolated incidents; they were a systemic validation for threat actors that compromising developer tools and libraries yield disproportionately high returns. Firmware exploits, particularly in network devices and endpoint security agents, are also on a disturbing upward trend, signaling a shift towards lower-
