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-wjpw-4j6x-6rwh 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 378,567 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.

Description
The Jetty URI parser has some key differences compared to other common parsers when evaluating invalid or unusual URIs. Specifically:
Invalid Scheme
| URI | Jetty | uri-js (nodejs) | node-url(nodejs) |
|---|---|---|---|
https>://vulndetector.com/path | scheme=http> | scheme=https | invalid URI |
Improper IPv4 mapped IPv6
| URI | Jetty | System.Uri(CSharp) | curl(C) |
|---|---|---|---|
http://[0:0:0:0:0:ffff:127.0.0.1] | invalid | host=[::ffff:127.0.0.1] | host=[::ffff:127.0.0.1] |
http://[::ffff:255.255.0.0] | invalid | host=[::ffff:255.255.0.0] | host=[::ffff:255.255.0.0] |
Incorrect IPv6 delimeter priority
| URI | Jetty | urllib3(python) | furl(python) | Spring | chromium |
|---|---|---|---|---|---|
http://[normal.com@]vulndetector.com/ | host=[normal.com@] | invalid | invalid | ||
http://normal.com[user@vulndetector].com/ | host=`[noirmal.com@vulndetector | host=normal.com | invalid | ||
http://normal.com[@]vulndetector.com/ | host=`normal.com[@] | host=normal.com | invalid |
Incorrect delimeter priority
| URI | Jetty | urllib3(python) | jersey |
|---|---|---|---|
http://normal.com/#@vulndetector.com | host=vulndetector.com | host=normal.com | host=normal.com |
http://normal.com/[email protected] | host=vulndetector.com | host=normal.com | host=normal.com |
Impact
Differential parsing of URIs in systems using multiple components may result in security by-pass. For example a component that enforces a black list may interpret the URIs differently from one that generates a response. At the very least, differential parsing may divulge implementation details.

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
No patched version of org.eclipse.jetty:jetty-http has shipped for GHSA-wjpw-4j6x-6rwh yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
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-wjpw-4j6x-6rwh can be triaged on real exposure rather than presence alone.
Tailored to GHSA-wjpw-4j6x-6rwh. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
This vulnerability is rated as Low by Red Hat. Successful usage of this vulnerability is non-trivial, as the attacker must be able to craft a URI that exploits Jetty's differential parsing while bypassing other parsers (ex. in a firewall or load balancer). Additionally, divulging implementation details is possible but…
