Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-46448 exists.\n\nAffected packages and fixed versions:\n- nova (PyPI): affected from 18.0.0; fixed in 31.3.1, 32.2.1, 33.0.2\n- nova (PyPI): affected from 18.0.0 up to 31.3.0; no fix listed\n- nova (PyPI): affected from 18.0.0 up to 31.3.0; no fix listed\n- nova (PyPI): affected from 32.0.0; fixed in 32.2.1\n- nova (PyPI): affected from 32.0.0; fixed in 32.2.1\n- nova (PyPI): affected from 33.0.0; fixed in 33.0.2\n- nova (PyPI): affected from 33.0.0; fixed in 33.0.2\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-2026-46448/ (Markdown: https://insights.sbomify.com/CVE-2026-46448/index.md)","id":"CVE-2026-46448","markdown":"https://insights.sbomify.com/CVE-2026-46448/index.md","name":"CVE-2026-46448","record":{"aliases":["DEBIAN-CVE-2026-46448","GHSA-mfg3-p6m3-gjgr","PYSEC-2026-2686","UBUNTU-CVE-2026-46448","USN-8434-1"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenStack Nova","requires_auth":"low_privilege","summary":"Attackers can create instances without proper resource allocation tracking, potentially bypassing quota enforcement in OpenStack Nova.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nova","vendor":"openstack"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-669","name":"Incorrect Resource Transfer Between Spheres"}],"description":"In OpenStack Nova before 33.0.2, the server create API does not strip certain hint data.
