Potential denial of service after connection migration
Blast Radius
s2n-quicReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
Impact
An issue in s2n-quic results in the endpoint shutting down due to a combination of peer-initiated connection migration and duplicate new connection ID frames being received. No AWS services are affected by this issue, and customers of AWS services do not need to take action.
Impacted versions: <=v1.24.0
Patches
The patch is included in v1.25.0.
Workarounds
There is no workaround. Applications using s2n-quic should upgrade their application to the most recent release of s2n-quic.
If you have any questions or comments about this advisory we ask that you contact AWS/Amazon Security via our vulnerability reporting page or directly via email to [email protected]. Please do not create a public GitHub issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for s2n-quic. 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 s2n-quic to 1.25.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rfhg-rjfp-9q8q 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-rfhg-rjfp-9q8q 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-rfhg-rjfp-9q8q. 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-rfhg-rjfp-9q8q in your dependencies?
O3 detects GHSA-rfhg-rjfp-9q8q across crates.io dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
