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-2026-2705 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-2026-2705/ (Markdown: https://insights.sbomify.com/CVE-2026-2705/index.md)","id":"CVE-2026-2705","markdown":"https://insights.sbomify.com/CVE-2026-2705/index.md","name":"CVE-2026-2705","record":{"aliases":["DEBIAN-CVE-2026-2705","GHSA-4w5w-4fhm-q483","PYSEC-2026-2770","UBUNTU-CVE-2026-2705"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Chemical library","requires_auth":"none","summary":"Open Babel library contains an out-of-bounds read vulnerability in MOL2 file handling, potentially allowing remote attackers to cause denial of service or execute code.","user_interaction":"required","vuln_class":"memory_corruption"},"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-125","name":"Out-of-bounds Read"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability was detected in Open Babel up to 3.1.1.
