CVE-2023-35932
HIGHCVE-2023-35932 is a high-severity (CVSS 7.1) CWE-77 vulnerability in jcvi. O3 Security confirms whether CVE-2023-35932 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
jcvi vulnerable to Configuration Injection due to unsanitized user input
Real-World Exposure
jcviReal-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
jcvi is a Python library to facilitate genome assembly, annotation, and comparative genomics. A configuration injection happens when user input is considered by the application in an unsanitized format and can reach the configuration file. A malicious user may craft a special payload that may lead to a command injection. The impact of a configuration injection may vary. Under some conditions, it may lead to command injection if there is for instance shell code execution from the configuration file values. This vulnerability does not currently have a fix.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for jcvi. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of jcvi has shipped for CVE-2023-35932 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 O3 protects you
O3 pinpoints whether CVE-2023-35932 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2023-35932. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-35932 in your dependencies?
O3 detects CVE-2023-35932 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
