Introducing Reachability Analysis to Triage Exploitable OSS Vulnerabilities

Keeping up with open source security alerts can feel like chasing ghosts — your scanner flags dozens of CVEs in your dependency tree, but not every vulnerable function is actually used in your code. That uncertainty slows teams down and clutters backlogs with findings that may never pose real risk.

To cut through that noise, Jit now adds reachability analysis to every Software Composition Analysis (SCA) finding. Instead of just telling you that a library includes a known vulnerability, Jit checks whether your code can actually reach and invoke the vulnerable part — and if so, exactly where that happens.

How Reachability Analysis Works

Not all vulnerabilities deserve the same urgency – a CVE in a library that your code never calls poses far less risk than one that’s actively reachable in runtime. 

Here’s how Jit users can focus on the open source vulnerabilities that actually matter. 

• Vulnerability reachability via code logic analysis: Jit scans your codebase and all declared dependencies, then builds a call graph that maps the relationships between your application logic and the libraries you use. Using this graph, we trace whether your code paths can invoke a vulnerable function inside a third-party component. If Jit finds a reachable path, the finding is automatically flagged with a positive reachability signal. This means the vulnerability isn’t theoretical — it’s actually exploitable in runtime. 

• Automated risk scoring and triage with AI Agents: That signal feeds directly into Jit’s Context Engine, which adjusts the Priority Score of the finding to reflect its actual runtime risk. Jit’s Sera (Security Evaluation and Risk Assessment Agent) incorporates this information during triage to weed out the noise and focus your attention on the real risks.

• Ownership traceability: By pinpointing where the vulnerable package resides, Jit can trace the reachable vulnerability back to the responsible development team – making it easy to hold the appropriate developers responsible.

By highlighting what’s really exposed, you spend less time triaging noise and more time fixing what counts. And when a reachable vulnerability is confirmed, Jit doesn’t just say it exists — it shows you where the vulnerable function is called in your code, making the remediation path much clearer.

Zero Configuration — Instant Insight

This capability runs automatically for every SCA finding — no manual configuration or extra setup needed. If reachability is confirmed, it’s instantly added as a built-in signal to help you triage faster and remediate smarter.

In short, you get fewer false alarms, clearer priorities, and better context — so you can shrink your backlog instead of expanding it.
