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-2020-12265 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- decompress (npm): affected all versions; fixed in 4.2.1\n- decompress (npm): affected all versions; fixed in 4.2.1\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-2020-12265/ (Markdown: https://insights.sbomify.com/CVE-2020-12265/index.md)","id":"CVE-2020-12265","markdown":"https://insights.sbomify.com/CVE-2020-12265/index.md","name":"CVE-2020-12265","record":{"aliases":["GHSA-qgfr-5hqp-vrw9","ROOT-APP-NPM-CVE-2020-12265"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js decompress package","requires_auth":"none","summary":"An attacker can write arbitrary files to the system via directory traversal in the decompress package when processing archives with symlinks.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"decompress","vendor":"decompress_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-59","name":"Improper Link Resolution Before File Access"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"The decompress package before 4.2.1 for Node.js is vulnerable to Arbitrary File Write via ../ in an archive member, when a symlink is used, because of Directory Traversal.","ecosystems":["npm"],"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":"Path Traversal in decompress","id":"CVE-2020-12265","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"path_traversal","year":"2020"},"n_packages":2,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2020-12266"},"packages":[{"ecosystem":"npm","fixed":["4.2.1"],"introduced":["0"],"last_affected":[],"package":"decompress","purl":null,"source":"GHSA-qgfr-5hqp-vrw9"},{"ecosystem":"npm","fixed":["4.2.1"],"introduced":["0"],"last_affected":[],"package":"decompress","purl":"pkg:npm/decompress","source":"GHSA-qgfr-5hqp-vrw9"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-12262"},"products":["n/a"],"published":"2020-04-26","related":[{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2026-39246","kev_date_added":null,"published":"2026-07-09"},{"cvss_score":6.2,"headline":"Path traversal in n/a","id":"CVE-2026-39245","kev_date_added":null,"published":"2026-07-09"},{"cvss_score":5.5,"headline":"decompress allows arbitrary hardlink creation during archive extraction","id":"CVE-2026-39243","kev_date_added":null,"published":"2026-07-09"}],"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":"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":"An attacker can write arbitrary files to the system via directory traversal in the decompress package when processing archives with symlinks.","url":"https://insights.sbomify.com/CVE-2020-12265/"}
