GHSA-cj7v-27pg-wf7q — jetty-http
LOWGHSA-cj7v-27pg-wf7q is a low-severity (CVSS 2.7) Improper Input Validation vulnerability in org.eclipse.jetty:jetty-http. A fix is available for org.eclipse.jetty:jetty-http — see the affected versions and patch details below.
Jetty invalid URI parsing may produce invalid HttpURI.authority
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-cj7v-27pg-wf7q plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,166 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-cj7v-27pg-wf7q can be triaged on real exposure rather than presence alone.
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 Security finds GHSA-cj7v-27pg-wf7q across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
