Transitive dependencies in cybersecurity refer to software components that are not directly included in a project but are brought in indirectly through other dependencies. For example, if your application uses Library A, and Library A depends on Library B, then Library B is a transitive dependency for your application. These dependencies can increase the attack surface because vulnerabilities in transitive dependencies may not be immediately visible or managed by the primary development team. Attackers often exploit such hidden vulnerabilities. Effective dependency management and regular security audits are essential to minimize risks associated with transitive dependencies.
