Open-source security debt grows across commercial software

Open source code sits inside nearly every commercial application, and development teams continue to add new dependencies. Black Duck’s 2026 Open Source Security and Risk Analysis Report data shows that nearly all audited codebases contain open source components, with average component counts rising sharply over the past year. That growth brings a parallel increase in exposure. Mean vulnerabilities per codebase climbed from 280 to 581 in one year, more than doubling. Median vulnerabilities also rose. … More → The post Open-source security debt grows across commercial software appeared first on Help Net Security.

AI-driven DAST reduces manual setup and surfaces exploitable vulnerabilities

In this Help Net Security interview, Joni Klippert, CEO at StackHawk, discusses what defines DAST coverage in 2026 and why scan completion does not equal security. She explains how AI-driven DAST testing automates attack surface discovery, supports business-logic testing in pre-production, and reduces the manual setup that has limited adoption. Klippert also describes how organizations can implement runtime testing without instrumenting production systems. In 2026, what does “good DAST coverage” mean, and how should teams … More → The post AI-driven DAST reduces manual setup and surfaces exploitable vulnerabilities appeared first on Help Net Security.
