The Vulnerable Dependencies Problem
Modern apps are 80% third-party libraries. If your npm or pip packages are vulnerable, your app is vulnerable.
Tool: Trivy
Trivy scans project dependencies for known CVEs (Common Vulnerabilities and Exposures).
Command:
trivy fs . (Scan the current filesystem).
It will give you a list of high/critical vulnerabilities in your package-lock.json or requirements.txt.
