Open-source dependencies introduce significant but often overlooked security risks. 86% of enterprise codebases contain at least one vulnerable open-source component, and 61% of dependencies are transitive, making full visibility difficult. Key threats include outdated/unmaintained libraries, transitive vulnerability chains, typosquatting and dependency confusion attacks, compromised maintainer accounts, and CI/CD pipeline infiltration. Real-world examples like Log4Shell, the Event-Stream npm attack, and the Codecov breach illustrate the severity. Mitigations include using SCA tools, generating SBOMs, adopting frameworks like Google's SLSA, enforcing 2FA for maintainer accounts, eliminating unmaintained libraries, and applying zero-trust principles to all open-source dependencies.
