CVE-2020-10800
HIGHCVE-2020-10800 is a high-severity (CVSS 8.1) vulnerability in lix. O3 Security confirms whether CVE-2020-10800 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Machine-In-The-Middle in lix
Real-World Exposure
lixReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.
Description
All versions of lix are vulnerable to Machine-In-The-Middle. The package accepts downloads with http and follows location header redirects for package downloads. This allows for an attacker in a privileged network position to intercept a lix package installation and redirect the download to a malicious source.
Recommendation
No fix is currently available. Consider using an alternative package until a fix is made available.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for lix. 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 lix has shipped for CVE-2020-10800 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-2020-10800 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-2020-10800. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
