An attacker can exploit it over the internet without logging in, 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-2026-3408 exists.\n\nAffected packages and fixed versions:\n- openbabel (PyPI): affected all versions; fixed in 3.2.0\n- openbabel (PyPI): affected all versions; fixed in 3.2.0\n- openbabel (PyPI): affected all versions; fixed in 3.2.0\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-2026-3408/ (Markdown: https://insights.sbomify.com/CVE-2026-3408/index.md)","id":"CVE-2026-3408","markdown":"https://insights.sbomify.com/CVE-2026-3408/index.md","name":"CVE-2026-3408","record":{"aliases":["DEBIAN-CVE-2026-3408","GHSA-rxpr-wq63-jr7p","PYSEC-2026-2791","UBUNTU-CVE-2026-3408"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Open Babel library","requires_auth":"none","summary":"A remote attacker can cause a denial of service via null pointer dereference in Open Babel's CDXML file handler.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"open_babel","vendor":"openbabel"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-404","name":"Improper Resource Shutdown or Release"}],"description":"A vulnerability was identified in Open Babel up to 3.1.1.
