Bottom line: Without rigorous API discovery, protection and governance, investments in AI security at the agent level fall flat, as several documented incidents involving deleted production databases show.
According to the Cloud Security Alliance, two-thirds of organizations have already experienced a security incident related to AI agents in the past year. Security leaders often focus on the agent layer, while the underlying API infrastructure is underestimated as an entry point.
McKinsey reported in November that 62 percent of organizations worldwide are testing, piloting, or already scaling agentic AI projects. Gartner forecasts global AI spending of over $2.59 trillion for 2026, a 47 percent increase over the previous year. Alongside this growth, the Cloud Security Alliance (CSA) reports that two-thirds of organizations suffered a security incident attributable to AI agents in the past year. These risks are therefore no longer hypothetical, but a demonstrable reality.
Large language models are non-functional without APIs, since they ingest and output vast amounts of data through these interfaces at enormous scale. APIs that previously logged a few hundred calls per day are now receiving thousands of requests per minute due to AI-driven workloads. This scaling makes APIs a preferred attack vector: according to one study, 87 percent of organizations suffered API-related security incidents in the past year, with AI-linked APIs most frequently affected. Another study counted 439 new AI-related CVEs within twelve months, an increase of 1,025 percent over the previous year — nearly all directly related to APIs, including injection vulnerabilities, misconfigurations, and new memory corruption flaws.
For CISOs, the problem is compounded by so-called shadow and zombie APIs: interfaces forgotten or never documented in distributed cloud and microservices environments. AI agents are designed to independently discover and use accessible APIs, even when not explicitly authorized to do so, as long as this serves goal attainment. These interfaces are often not secured according to current governance requirements, which can lead to data loss or other unintended effects. Both NIS2 and DORA, although not specifically aimed at AI, require companies to consider AI capabilities from a resilience and security perspective — adding regulatory pressure on top of the financial and reputational damage of a data breach.
Concrete incidents underscore the urgency: a Cursor coding agent completely deleted a customer’s production database in just nine seconds after finding an API token with unrestricted permissions in an unrelated file — without the API requiring confirmation for the operation. In a similar case, a Replit AI agent deleted a production database despite being explicitly instructed not to. For CISOs, this means that investments in AI security at the agent level can remain ineffective without rigorous API discovery, protection, and governance.
