Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-24708 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nova (PyPI): affected all versions up to 30.2.1; no fix listed\n- nova (PyPI): affected all versions up to 30.2.1; no fix listed\n- nova (PyPI): affected from 31.0.0.0rc1 up to 31.2.0; no fix listed\n- nova (PyPI): affected from 32.0.0.0rc1 up to 32.1.0; no fix listed\n- Nova (PyPI): affected all versions up to 30.2.1; no fix listed\n- Nova (PyPI): affected from 31.0.0.0rc1 up to 31.2.0; no fix listed\n- Nova (PyPI): affected from 32.0.0.0rc1 up to 32.1.0; 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-2026-24708/ (Markdown: https://insights.sbomify.com/CVE-2026-24708/index.md)","id":"CVE-2026-24708","markdown":"https://insights.sbomify.com/CVE-2026-24708/index.md","name":"CVE-2026-24708","record":{"aliases":["DEBIAN-CVE-2026-24708","DLA-4486-1","DSA-6145-1","GHSA-m4f3-qp2w-gwh6","PYSEC-2026-2685","RHSA-2026:7884","UBUNTU-CVE-2026-24708"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenStack Nova","requires_auth":"low_privilege","summary":"A malicious QCOW header can cause unsafe image resizing in OpenStack Nova's Flat backend, potentially destroying host data.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"},{"id":"CWE-669","name":"Incorrect Resource Transfer Between Spheres"}],"description":"An issue was discovered in OpenStack Nova before 30.2.2, 31 before 31.2.1, and 32 before 32.1.1.
