An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-5851 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- python-docx (PyPI): affected all versions; fixed in 0.8.6\n- python-docx (PyPI): affected all versions; fixed in 0.8.6\n- python-docx (PyPI): affected all versions; fixed in 0.8.6\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-2016-5851/ (Markdown: https://insights.sbomify.com/CVE-2016-5851/index.md)","id":"CVE-2016-5851","markdown":"https://insights.sbomify.com/CVE-2016-5851/index.md","name":"CVE-2016-5851","record":{"aliases":["GHSA-34wj-p5jm-2p96","PYSEC-2016-21"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python document library","requires_auth":"none","summary":"Attackers can exploit XML External Entity vulnerabilities in python-docx to read sensitive files or cause denial of service via crafted documents.","user_interaction":"required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"python-docx","vendor":"python-openxml_project"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"python-docx before 0.8.6 allows context-dependent attackers to conduct XML External Entity (XXE) attacks via a crafted document.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Improper Restriction of XML External Entity Reference in python-docx","id":"CVE-2016-5851","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"xxe","year":"2016"},"n_packages":3,"n_references":7,"next":{"headline":"Privilege escalation in Quadro, NVS, GeForce (all versions)","id":"CVE-2016-5852"},"packages":[{"ecosystem":"PyPI","fixed":["0.8.6"],"introduced":["0"],"last_affected":[],"package":"python-docx","purl":null,"source":"GHSA-34wj-p5jm-2p96"},{"ecosystem":"PyPI","fixed":["0.8.6"],"introduced":["0"],"last_affected":[],"package":"python-docx","purl":"pkg:pypi/python-docx","source":"GHSA-34wj-p5jm-2p96"},{"ecosystem":"PyPI","fixed":["0.8.6"],"introduced":["0"],"last_affected":[],"package":"python-docx","purl":"pkg:pypi/python-docx","source":"PYSEC-2016-21"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2016-5850"},"products":["n/a"],"published":"2016-12-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Attackers can exploit XML External Entity vulnerabilities in python-docx to read sensitive files or cause denial of service via crafted documents.","url":"https://insights.sbomify.com/CVE-2016-5851/"}
