Real-World Exposure
org.eclipse.jetty:jetty-serverReal-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
In Eclipse Jetty versions 9.4.0 to 9.4.56 a buffer can be incorrectly released when confronted with a gzip error when inflating a request body. This can result in corrupted and/or inadvertent sharing of data between requests.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

jettyeclipseDetection & 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-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.eclipse.jetty:jetty-server to 9.4.57.v20241219 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q4rv-gq96-w7c5 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.
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 an IMPORTANT severity because a buffer management vulnerability exists within the GzipHandler's buffer release mechanism when encountering gzip errors during request body inflation, this flaw can lead to the incorrect release and subsequent inadvertent sharing and corruption of request…
