Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-3637 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- neutron (PyPI): affected all versions up to 22.0.2; no fix listed\n- neutron (PyPI): affected all versions up to 22.0.2; no fix listed\n- neutron (PyPI): affected all versions up to 22.0.2; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-3637/ (Markdown: https://insights.sbomify.com/CVE-2023-3637/index.md)","id":"CVE-2023-3637","markdown":"https://insights.sbomify.com/CVE-2023-3637/index.md","name":"CVE-2023-3637","record":{"aliases":["GHSA-r3jh-qhgj-gvr8","PYSEC-2026-1694","RHSA-2023:4283","UBUNTU-CVE-2023-3637"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenStack Neutron","requires_auth":"low_privilege","summary":"An authenticated user can cause denial of service by creating unconstrained security groups via invalid project queries in OpenStack Neutron.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"openstack_platform","vendor":"redhat"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"An uncontrolled resource consumption flaw was found in openstack-neutron.
