Zero In on Actual Third-Party Vulnerabilities

Typical SCA (Software Composition Analysis) and dependency analysis tools alert you when you’re using a library with a known CVE. But they don’t tell you if your source code actually contains the vulnerable lines of code. This leads to more noise and potentially wasted effort.

FossID Vulnerable Snippet Finder goes deeper. We pinpoint the actual lines of vulnerable code inside your codebase — whether you imported the package, copy-pasted a fragment, or integrated AI-generated code. This enables your teams to focus on real risk only.

detection beyond metadata

Vulnerability Detection That Goes Beyond Metadata

FossID’s Vulnerable Snippet Finder is an extension of our industry-leading code snippet detection technology to identify:

Actual vulnerable code
Not just the package name or version, but the specific lines of code tied to a known CVE.
AI-generated and copy-pasted code fragments
Even if you didn’t declare a package, FossID finds the risk if the code is in your product.
Modified or refactored code
The 6-line detection threshold of our digital fingerprinting identifies code regardless of formatting along with resilience to renaming or restructuring.

How It Works

FossID is able to identify the existence of vulnerable code and pinpoint the location within your source code through the combination of three techniques:

1

Deep Code Snippet Detection

First, FossID’s patented snippet detection methodology scans your source code for the existence of open source libraries with a configurable sensitivity-level as precise as just 6-lines of code.

2

Open Source Knowledge Base

FossID’s massive and constantly curated open source knowledge base contains source code of over 200 million software components. This comprehensive and current data is fundamental to automatic identification and CVE alerting.

3

Vulnerable Snippet Database

This is where FossID goes the next step – our open source knowledge base also includes a volume of over 200,000 vulnerable code snippets from the CVE volume so we can identify with 100% certainty the existence of the library’s vulnerable code.

Why Vulnerable Snippet Detection Matters

Eliminate False Positives

By matching only the proven vulnerable lines of code, FossID lets you confidently prioritize what really matters.

Save Time and Resources

Stop wasting time on unnecessary patching or chasing theoretical risks that don’t exist in your code.

Meet Regulatory and Customer Requirements

Deliver evidence of actual risk exposure to legal, security, and customer stakeholders.

Address the New Reality of AI-Generated Code

Catch hidden vulnerabilities introduced by AI coding assistants that other SCA tools can’t detect.

proven precision

Find Vulnerable Snippets with Unmatched Precision

FossID Vulnerable Snippet Finder is the most precise solution on the market, detecting real vulnerable code down to 6 lines.

Because knowing you could have a vulnerability isn’t enough. You need to know for sure and where it is located.
