What is GHSA-9PPR-WFW9-XVR2?

GHSA-9PPR-WFW9-XVR2 is a medium-severity security vulnerability in github.com/tinfoil-factory/netfoil (go), affecting versions >= 0.3.0, < 0.6.1. It is fixed in 0.6.1.

Which versions of github.com/tinfoil-factory/netfoil are affected by GHSA-9PPR-WFW9-XVR2?

github.com/tinfoil-factory/netfoil (go) versions >= 0.3.0, < 0.6.1 is affected.

Is there a fix for GHSA-9PPR-WFW9-XVR2?

Yes. GHSA-9PPR-WFW9-XVR2 is fixed in 0.6.1. Upgrade to this version or later.

Is GHSA-9PPR-WFW9-XVR2 exploitable, and should I be worried?

Whether GHSA-9PPR-WFW9-XVR2 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether GHSA-9PPR-WFW9-XVR2 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
