Summary
netfoil has a domain name filter bypass via multiple questions
Potential bypass of domain name filter by crafting a DNS request with multiple questions, with the first question being legitimate.
Impact
Depends on a local attackers ability to craft multiple questions and the remote DoH server supporting them.
Affected versions
Security releases
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.

Frequently Asked Questions
- What is GHSA-59QP-CFJ3-RP64? GHSA-59QP-CFJ3-RP64 is a medium-severity security vulnerability in github.com/tinfoil-factory/netfoil (go), affecting versions < 0.3.0. It is fixed in 0.3.0.
- Which versions of github.com/tinfoil-factory/netfoil are affected by GHSA-59QP-CFJ3-RP64? github.com/tinfoil-factory/netfoil (go) versions < 0.3.0 is affected.
- Is there a fix for GHSA-59QP-CFJ3-RP64? Yes. GHSA-59QP-CFJ3-RP64 is fixed in 0.3.0. Upgrade to this version or later.
- Is GHSA-59QP-CFJ3-RP64 exploitable, and should I be worried? Whether GHSA-59QP-CFJ3-RP64 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-59QP-CFJ3-RP64 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.
