GHSA-cj7v-27pg-wf7q
LOWGHSA-cj7v-27pg-wf7q is a low-severity (CVSS 2.7) Improper Input Validation vulnerability in org.eclipse.jetty:jetty-http. O3 Security confirms whether GHSA-cj7v-27pg-wf7q is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Jetty invalid URI parsing may produce invalid HttpURI.authority

org.eclipse.jetty:jetty-http☕org.eclipse.jetty:jetty-http☕org.eclipse.jetty:jetty-httpReal-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
Description
URI use within Jetty's HttpURI class can parse invalid URIs such as http://localhost;/path as having an authority with a host of localhost;.
A URIs of the type http://localhost;/path should be interpreted to be either invalid or as localhost; to be the userinfo and no host.
However, HttpURI.host returns localhost; which is definitely wrong.
Impact
This can lead to errors with Jetty's HttpClient, and Jetty's ProxyServlet / AsyncProxyServlet / AsyncMiddleManServlet wrongly interpreting an authority with no host as one with a host.
Patches
Patched in PR #8146 for Jetty version 9.4.47. Patched in PR #8014 for Jetty versions 10.0.10, and 11.0.10
Workarounds
None.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.eclipse.jetty:jetty-http. 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.
Fix
Update org.eclipse.jetty:jetty-http to 9.4.47 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cj7v-27pg-wf7q 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.
How O3 protects you
O3 pinpoints whether GHSA-cj7v-27pg-wf7q 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-cj7v-27pg-wf7q. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-cj7v-27pg-wf7q in your dependencies?
O3 detects GHSA-cj7v-27pg-wf7q across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
