Wallarm has released its 2026 API ThreatStats Report, a comprehensive analysis of API attack telemetry, published vulnerabilities, confirmed exploits, and disclosed breaches from 2025. The findings position APIs as the single most exploited attack surface in modern environments, far beyond theoretical risk, with attackers capitalizing on repeatable failures in identity, access control, and exposed interfaces—often at machine speed and massive scale.
The report highlights a clear shift: APIs are no longer just an AppSec concern—they are the primary gateway for real-world exploitation. Attackers exploit predictable weaknesses in identity handling and exposed surfaces, turning familiar gaps into scalable, high-impact breaches when amplified by automation and AI.
“API security is at the heart of any AI transformation,” said Ivan Novikov, Founder & CEO at Wallarm. “Every AI application or agent interaction is mediated through an API. API security is integral to successful AI adoption, and AI by its very nature has made the consequences of getting it wrong much larger and much more impactful.”
The rise of agentic AI introduces new risks, with MCP emerging as a critical control plane vulnerability. MCP-related issues showed explosive growth and direct ties to large-scale exposures, signaling where API threats are headed as AI agents proliferate.
The data reinforces that the most damaging incidents stem from repeatable, preventable gaps—not sophisticated zero-days. Traditional detection tools fall short against fast, remote, low-effort attacks that require real-time blocking.
For CISOs, the message is clear: strengthening AI security starts with APIs. Effective defense focuses on systematic improvements in identity management, exposure reduction, and abuse prevention—before scale and automation turn manageable risks into material business impact.
