What is GHSA-3GXF-9R58-2GHG?

GHSA-3GXF-9R58-2GHG is a medium-severity security vulnerability in openssl (rust), affecting versions >= 0.9.7, < 0.10.48. It is fixed in 0.10.48.

Which versions of openssl are affected by GHSA-3GXF-9R58-2GHG?

openssl (rust) versions >= 0.9.7, < 0.10.48 is affected.

Is there a fix for GHSA-3GXF-9R58-2GHG?

Yes. GHSA-3GXF-9R58-2GHG is fixed in 0.10.48. Upgrade to this version or later.

Is GHSA-3GXF-9R58-2GHG exploitable, and should I be worried?

Whether GHSA-3GXF-9R58-2GHG 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-3GXF-9R58-2GHG 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.

Summary

openssl X509NameBuilder::build returned object is not thread safe

OpenSSL has a modified bit that it can set on on X509_NAME objects. If this bit is set then the object is not thread-safe even when it appears the code is not modifying the value.

Thanks to David Benjamin (Google) for reporting this issue.

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.
