GHSA-3832-9276-x7gf
GHSA-3832-9276-x7gf is a CWE-295 vulnerability in commons-httpclient:commons-httpclient. O3 Security confirms whether GHSA-3832-9276-x7gf is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Improper Certificate Validation in Apache Commons HttpClient
Blast Radius
commons-httpclient:commons-httpclientReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Apache Commons HttpClient 3.x, as used in Amazon Flexible Payments Service (FPS) merchant Java SDK and other products, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
Note that the Commons HttpClient project is end of life. It has been replaced by the Apache HttpComponents project in its HttpClient and HttpCore modules. CVE-2012-5783 has been patched in v4.0 of the Apache HttpComponents HttpClient module.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for commons-httpclient:commons-httpclient. 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 commons-httpclient:commons-httpclient has shipped for GHSA-3832-9276-x7gf 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 GHSA-3832-9276-x7gf 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 GHSA-3832-9276-x7gf. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
