SCA in practice: vulnerability management becomes part of the build process

Expert at SOCWISE

Transitive dependencies can hide serious vulnerabilities from developers. Learn how SCA exposes the full dependency chain and guides safer remediation.

In our previous article, we explained why it has become a fundamental security issue to have a clear understanding of exactly which open-source and third-party components our applications are built from. However, Software Composition Analysis (SCA) doesn’t truly add value simply by running an occasional report on the packages; it adds value when it’s integrated into the development lifecycle and supports day-to-day decisions made by developers, security teams, and business leaders.

The practical question isn’t just whether there are any vulnerable components in the application. It’s also:

when and in which build it appeared,
which branch or developer change it is associated with,
whether it is accessible at runtime,
whether it can actually be exploited,
and what should be done about it: fix, triage, exception handling, or release blocking.

A well-structured SCA process provides evidence-based answers to these questions.

Why is it a good idea to integrate SCA into the pipeline?

Rapid feedback is crucial in the development process. If a vulnerable component is only identified days or weeks later in a separate report, it becomes more difficult to link the fix to the specific developer change. However, if the SCA scan runs as part of the build, the team can immediately see what risks a particular change has introduced.

SCA integrated into the CI/CD pipeline is useful in several ways:

it automatically checks the packages included in the build,
it flags vulnerable direct and transitive dependencies,
it links the findings to the specific build and branch,
it can halt the process based on policy,
and it forces the team to perform documented triage in critical cases.

The goal is not for every finding to halt development. A successful implementation is gradual: first, we make the problems visible, then we tighten the policies based on the application’s criticality and the team’s maturity.

The build gate is not a penalty, but a checkpoint

The essence of a policy-based build gate is to ensure that critical risks do not slip unnoticed into the next step of the development process. If the pipeline fails due to a vulnerability, the first reaction should not be, “The tool is hindering our work.” Rather, it should be that the system has reached a checkpoint where a decision must be made.

This decision can take several forms:

updating the vulnerable package,
modifying the dependency chain,
documenting the finding as a false positive,
adding a temporary policy exception,
or blocking the release if the risk is indeed high.

It is important that the build gate not be too general. For a business-critical application serving external customers, it may be justified to fail the build in the event of a critical vulnerability or one with a known exploit. For a less critical internal component, it may be sufficient to issue a warning and open a ticket.

Not every critical hit poses a real risk

SCA tools often correctly indicate that a vulnerable component is present in the application. However, this alone does not prove that the vulnerability can be exploited.

For example, a package may indeed be installed, but the application may not use the function through which the vulnerability would be triggered. In such cases, the alert is correct at the component level, but in the context of the application, it does not necessarily represent a real attack surface.

This is why joint triage between developers and the security team is necessary. The security team sees the vulnerability context, while the developer can confirm whether the package or function in question is actually part of the running logic.

A decision to dismiss a false positive is justifiable only if it is backed by evidence. It is not enough to simply say, “We don’t use this.” For example, the following must be documented:

which component is involved,
through which dependency path it was introduced,
which vulnerable function would be affected,
whether the application uses this code path,
who reviewed it,
who approved it,
and how long the exception remains valid.

This is also important from an auditability perspective. During a later audit, the question will not be whether a match was found, but rather what decision was made about it, on what evidence, and whether the process can be traced.

When transitive dependency is a real problem

In practice, many serious vulnerabilities do not appear as direct dependencies, but rather as transitive dependencies introduced by another package. This is dangerous because developers often do not even come across the name of the affected package directly.

For example, a web framework might include a query processing component that contains a known vulnerability. If this component is part of the running application and is connected to a code path accessible via an HTTP request, then this is no longer simply a theoretical risk.

In such cases, the added value of SCA becomes particularly evident. It not only shows that there is a vulnerable package, but also:

which direct package it was introduced through,
which version is affected,
whether a patched version is available,
what the dependency tree looks like,
and what update path is recommended.

A fix often does not mean trying to overwrite the deep-seated transitive package directly. A safer approach may be to update the direct dependency to a version that already includes the fixed transitive dependency.

When should we fix the problem immediately, and when should we triage it?

One of the most important practical questions in vulnerability management is when to apply a patch immediately and when to conduct a more thorough triage. There is no one-size-fits-all answer, but there are useful decision-making criteria.

An immediate patch is typically the best course of action if:

a stable, compatible patched version is available,
the upgrade does not cause significant architectural changes,
it involves a runtime dependency,
the package is connected to an external attack surface,
a critical or high-severity vulnerability is involved,
a known exploit is available,
or the fix can be implemented and tested more quickly than a lengthy analysis.

In the case of an advisory, it is important to quickly assess the impact

The value of SCA doesn’t end with the build. A component considered secure today may turn out tomorrow to contain a critical vulnerability. That’s why it’s important to be able to respond quickly when a new security advisory, vendor notice, or threat intelligence alert is issued: Are we affected?

In such a situation, it’s not enough to simply know that the vulnerability exists. You need to determine:

which applications use the affected component,
which versions are in use,
which component is business-critical,
whether it is accessible from the outside,
whether it handles sensitive or transactional data,
whether the conditions for exploitation are met,
and whether there is a known, actively exploited attack pattern.

If the same vulnerability appears in multiple components, it may not necessarily need to be treated with the same priority everywhere. A backend service handling customer transactions may take precedence in the patch order over an internal module with restricted access.

The most important lesson

The practical value of SCA does not lie solely in identifying vulnerabilities. In a large application, there will always be findings, and the number of them may even seem alarming at first glance. The question is whether the organization is capable of turning these into manageable, prioritized, and business-relevant tasks.

SCA integrated into the CI/CD pipeline, helps with this. It makes visible which components make up the application, in which build a risk appears, through which dependency chain it enters, and when the process needs to be stopped.

Evidence-based triage, in turn, helps ensure that not every finding is treated the same way. Some issues need to be fixed immediately. Some warrant deeper analysis. And some can be treated as documented exceptions if they truly do not pose an exploitable risk.

SCA is thus not just another security tool in the pipeline, but a control layer between development, security, and business risk management.
