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-rggv-cv7r-mw98 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.

Description
Impact
If an HTTP/2 connection gets TCP congested, when an idle timeout occurs the HTTP/2 session is marked as closed, and then a GOAWAY frame is queued to be written. However it is not written because the connection is TCP congested. When another idle timeout period elapses, it is then supposed to hard close the connection, but it delegates to the HTTP/2 session which reports that it has already been closed so it does not attempt to hard close the connection.
This leaves the connection in ESTABLISHED state (i.e. not closed), TCP congested, and idle.
An attacker can cause many connections to end up in this state, and the server may run out of file descriptors, eventually causing the server to stop accepting new connections from valid clients.
The client may also be impacted (if the server does not read causing a TCP congestion), but the issue is more severe for servers.
Patches
Patched versions:
- 9.4.54
- 10.0.20
- 11.0.20
- 12.0.6
Workarounds
Disable HTTP/2 and HTTP/3 support until you can upgrade to a patched version of Jetty. HTTP/1.x is not affected.

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.http2:http2-common, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.eclipse.jetty.http2:http2-common to 9.4.54 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rggv-cv7r-mw98 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-rggv-cv7r-mw98 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-rggv-cv7r-mw98. 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.
The issue in Jetty where HTTP/2 connections can enter a congested, idle state and potentially exhaust server file descriptors represents a moderate severity due to its impact on system resources and service availability. While the vulnerability requires the deliberate creation of numerous congested connections by an…
