An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-18705 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- quokka (PyPI): affected all versions; no fix listed\n- quokka (PyPI): affected all versions up to 0.4.0; no fix listed\n- quokka (PyPI): affected all versions up to 0.4.0; 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-2020-18705/ (Markdown: https://insights.sbomify.com/CVE-2020-18705/index.md)","id":"CVE-2020-18705","markdown":"https://insights.sbomify.com/CVE-2020-18705/index.md","name":"CVE-2020-18705","record":{"aliases":["GHSA-4q2r-qxp6-h5j6","PYSEC-2021-145"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Python web framework","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via XML External Entity injection in the Quokka Python web framework.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"quokka","vendor":"quokka_project"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"XML External Entities (XXE) in Quokka v0.4.0 allows remote attackers to execute arbitrary code via the component 'quokka/core/content/views.py'.","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":false,"headline":"Improper Restriction of XML External Entity Reference in Quokka","id":"CVE-2020-18705","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"xxe","year":"2020"},"n_packages":3,"n_references":1,"next":{"headline":"SQL injection in n/a","id":"CVE-2020-18713"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":[],"package":"quokka","purl":"pkg:pypi/quokka","source":"PYSEC-2021-145"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.4.0"],"package":"quokka","purl":null,"source":"GHSA-4q2r-qxp6-h5j6"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.4.0"],"package":"quokka","purl":"pkg:pypi/quokka","source":"GHSA-4q2r-qxp6-h5j6"}],"prev":{"headline":"Unrestricted Upload of File with Dangerous Type in django-widgy","id":"CVE-2020-18704"},"products":["n/a"],"published":"2021-08-16","related":[{"cvss_score":9.8,"headline":"Improper Restriction of XML External Entity Reference in Quokka","id":"CVE-2020-18703","kev_date_added":null,"published":"2021-08-16"},{"cvss_score":6.1,"headline":"Cross Site Scripting (XSS) in Quokka","id":"CVE-2020-18702","kev_date_added":null,"published":"2021-08-16"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via XML External Entity injection in the Quokka Python web framework.","url":"https://insights.sbomify.com/CVE-2020-18705/"}
