Definition

A security flaw in a third-party library or package your application depends on — which attackers can exploit even if your own code is perfectly secure.

خلل أمني في مكتبة أو حزمة طرف ثالث يعتمد عليها تطبيقك — يمكن للمهاجمين استغلاله حتى لو كان كودك الخاص آمناً تماماً.

Why It Matters

You write 500 lines of code but import 50,000 lines of dependencies. Your security posture is only as strong as the weakest dependency. `npm audit` takes 2 seconds and should run in every CI pipeline.

تكتب 500 سطر كود لكنك تستورد 50000 سطر من التبعيات. يعتمد وضعك الأمني على أضعف تبعية. يستغرق `npm audit` ثانيتين ويجب تشغيله في كل خط CI.

Full Definition

Modern applications have hundreds or thousands of transitive dependencies. Any one can contain a vulnerability (CVE). When a CVE is published, attackers actively scan for applications using the affected version. Tools: `npm audit` identifies known vulnerable packages; Dependabot (GitHub) automatically opens PRs to update vulnerable deps; Snyk and Socket provide deeper supply chain analysis. Severity levels (CVSS): Low, Medium, High, Critical. High-severity vulnerabilities in widely-used packages can affect millions of applications (e.g., Log4Shell in Log4j).
التطبيقات الحديثة لها مئات التبعيات العابرة. عند نشر ثغرة CVE، يفحص المهاجمون التطبيقات التي تستخدم الإصدار المتأثر. `npm audit` يُحدد الحزم الضعيفة. يمكن لثغرة واحدة في حزمة شائعة التأثير على ملايين التطبيقات.

Knowledge Graph

Avoid these mistakes when using Dependency Vulnerability:

1

Ignoring `npm audit` warnings as routine noise → HIGH and CRITICAL findings in production dependencies are actionable, not advisory. Fix them before deploying.

2

Only auditing direct dependencies → Transitive (indirect) dependencies are equally exploitable and often more dangerous — `npm audit` covers the whole tree.

3

Updating only the package.json version without running `npm install` → The lockfile must be updated too, or the vulnerable version is still installed. Always run `npm install` after updating.
