Summary
Vulnerable OpenSSL included in cryptography wheels
pyca/cryptography's wheels include a statically linked copy of OpenSSL. The versions of OpenSSL included in cryptography 37.0.0-38.0.3 are vulnerable to a number of security issues. More details about the vulnerabilities themselves can be found in https://www.openssl.org/news/secadv/20221101.txt.
If you are building cryptography source ("sdist") then you are responsible for upgrading your copy of OpenSSL. Only users installing from wheels built by the cryptography project (i.e., those distributed on PyPI) need to update their cryptography versions.

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-39HC-V87J-747X? GHSA-39HC-V87J-747X is a medium-severity security vulnerability in cryptography (pip), affecting versions >= 37.0.0, < 38.0.3. It is fixed in 38.0.3.
- Which versions of cryptography are affected by GHSA-39HC-V87J-747X? cryptography (pip) versions >= 37.0.0, < 38.0.3 is affected.
- Is there a fix for GHSA-39HC-V87J-747X? Yes. GHSA-39HC-V87J-747X is fixed in 38.0.3. Upgrade to this version or later.
- Is GHSA-39HC-V87J-747X exploitable, and should I be worried? Whether GHSA-39HC-V87J-747X 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-39HC-V87J-747X 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.
