It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-44512 exists.\n\nAffected packages and fixed versions:\n- onnx (PyPI): affected from 1.9.0; fixed in 1.22.0\n- onnx (PyPI): affected from 1.9.0; fixed in 1.22.0\n- onnx (PyPI): affected from 1.9.0; fixed in 1.22.0\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-2026-44512/ (Markdown: https://insights.sbomify.com/CVE-2026-44512/index.md)","id":"CVE-2026-44512","markdown":"https://insights.sbomify.com/CVE-2026-44512/index.md","name":"CVE-2026-44512","record":{"aliases":["DEBIAN-CVE-2026-44512","ECHO-584a-b2f6-d7a8","GHSA-hwpq-hmq9-wj77","PYSEC-2026-2689","UBUNTU-CVE-2026-44512"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ONNX machine learning library","requires_auth":"none","summary":"An attacker can cause a denial of service by providing a malicious ONNX model with zero inputs to the version converter.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"onnx","vendor":"linuxfoundation"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability.
