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-2021-20066 in the wild and no public exploit code.\n\nAffected product: JSDom. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2021-20066/ (Markdown: https://insights.sbomify.com/CVE-2021-20066/index.md)","id":"CVE-2021-20066","markdown":"https://insights.sbomify.com/CVE-2021-20066/index.md","name":"CVE-2021-20066","record":{"aliases":["UBUNTU-CVE-2021-20066"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"JSDom library","requires_auth":"none","summary":"JSDom allows malicious web pages to access and modify local files when script execution is enabled, risking data exposure and integrity.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"jsdom","vendor":"jsdom_project"}],"cvss":{"score":5.6,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[],"description":"JSDom improperly allows the loading of local resources, which allows for local files to be manipulated by a malicious web page when script execution is enabled.","ecosystems":[],"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":"Path traversal in JSDom","id":"CVE-2021-20066","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Missing authorization in Racom MIDGE Firmware","id":"CVE-2021-20067"},"packages":[],"prev":{"headline":"Other in SonicWall Global VPN Client","id":"CVE-2021-20051"},"products":["JSDom"],"published":"2021-02-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"JSDom allows malicious web pages to access and modify local files when script execution is enabled, risking data exposure and integrity.","url":"https://insights.sbomify.com/CVE-2021-20066/"}
