How severe is GHSA-jr9m-v5qh-mh2j?

GHSA-jr9m-v5qh-mh2j has a CVSS score of 6.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-jr9m-v5qh-mh2j?

GHSA-jr9m-v5qh-mh2j affects the following packages: neutron (PyPI), neutron (PyPI), neutron (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-jr9m-v5qh-mh2j?

Update neutron to 11.0.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jr9m-v5qh-mh2j is resolved across your whole dependency graph.

How do I detect GHSA-jr9m-v5qh-mh2j in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for neutron. 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.

How do I mitigate GHSA-jr9m-v5qh-mh2j if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-jr9m-v5qh-mh2j?

O3 pinpoints whether GHSA-jr9m-v5qh-mh2j is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-jr9m-v5qh-mh2j actively exploited in the wild?

No public exploit code has been indexed for GHSA-jr9m-v5qh-mh2j yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-jr9m-v5qh-mh2j?

GHSA-jr9m-v5qh-mh2j has an EPSS (Exploit Prediction Scoring System) score of 1.8%, placing it in the 75th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was GHSA-jr9m-v5qh-mh2j published, and has it been updated?

GHSA-jr9m-v5qh-mh2j was published on May 13, 2022 and was last updated on December 7, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

An issue was discovered in OpenStack Neutron 11.x before 11.0.7, 12.x before 12.0.6, and 13.x before 13.0.3. By creating two security groups with separate/overlapping port ranges, an authenticated user may prevent Neutron from being able to configure networks on any compute nodes where those security groups are present, because of an Open vSwitch (OVS) firewall KeyError. All Neutron deployments utilizing neutron-openvswitch-agent are affected.
