How severe is GHSA-5cpq-8wj7-hf2v?

No CVSS score has been assigned to GHSA-5cpq-8wj7-hf2v yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-5cpq-8wj7-hf2v?

GHSA-5cpq-8wj7-hf2v affects the following packages: cryptography (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-5cpq-8wj7-hf2v?

Update cryptography to 41.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5cpq-8wj7-hf2v is resolved across your whole dependency graph.

How do I detect GHSA-5cpq-8wj7-hf2v in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cryptography, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-5cpq-8wj7-hf2v if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-5cpq-8wj7-hf2v?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-5cpq-8wj7-hf2v can be triaged on real exposure rather than presence alone.

Is GHSA-5cpq-8wj7-hf2v actively exploited in the wild?

No public exploit code has been indexed for GHSA-5cpq-8wj7-hf2v yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

When was GHSA-5cpq-8wj7-hf2v published, and has it been updated?

GHSA-5cpq-8wj7-hf2v was published on June 2, 2023 and was last updated on September 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

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.

Detection & mitigation playbook

Open-source dependency

Detect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cryptography, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update cryptography to 41.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5cpq-8wj7-hf2v is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Tailored to GHSA-5cpq-8wj7-hf2v. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Frequently Asked Questions

pyca/cryptography's wheels include a statically linked copy of OpenSSL. The versions of OpenSSL included in cryptography 0.5-40.0.2 are vulnerable to a security issue. More details about the vulnerability itself can be found in https://www.openssl.org/news/secadv/20230530.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.

O3 Security · Impact-Aware SCA

Is GHSA-5cpq-8wj7-hf2v in your dependencies?

O3 Security finds GHSA-5cpq-8wj7-hf2v across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
