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-2026-19693 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- extract-zip (npm): affected all versions up to 2.0.1; no fix listed\n- extract-zip (npm): affected all versions up to 2.0.1; 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-2026-19693/ (Markdown: https://insights.sbomify.com/CVE-2026-19693/index.md)","id":"CVE-2026-19693","markdown":"https://insights.sbomify.com/CVE-2026-19693/index.md","name":"CVE-2026-19693","record":{"aliases":["DEBIAN-CVE-2026-19693","GHSA-7pqw-9j4j-h8q3","MINI-228c-c4q8-7jg7","MINI-25cm-7j39-244h","MINI-3v9g-j92w-r22r","MINI-577w-8hfx-p5px","MINI-6frx-wh8f-jhxw","MINI-6pgx-mhf2-8x7g","MINI-g53q-3hff-5jgw","MINI-gq7p-r26g-4xc2","MINI-jvcw-58cj-v83g","MINI-p7r4-gp65-xr2m","MINI-p9hq-rw2p-h9gm","MINI-r6wj-5wwr-wv6w","MINI-wr8h-h2w5-xc3x","MINI-wxrf-237w-rxqg","MINI-x9mp-x4gp-qw37","ROOT-APP-NPM-CVE-2026-19693","UBUNTU-CVE-2026-19693"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js zip extraction library","requires_auth":"none","summary":"Attackers can write arbitrary files outside the destination directory by exploiting symlink handling in extract-zip, potentially leading to code execution.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"seal","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/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":"extract-zip through 2.0.1 containment-checks only the parent directory of each archive entry and never the entry's own final path component, so an archive containing two entries with identical names - a symlink whose target is outside the destination, followed by a regular file - writes through the planted symlink and yields an arbitrary file write outside the destination directory.","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":"extract-zip arbitrary file write outside the destination directory via a symlink at the final path component","id":"CVE-2026-19693","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"Heap-based Buffer Overflow in Wireshark","id":"CVE-2026-19694"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["2.0.1"],"package":"extract-zip","purl":null,"source":"GHSA-7pqw-9j4j-h8q3"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["2.0.1"],"package":"extract-zip","purl":"pkg:npm/extract-zip","source":"GHSA-7pqw-9j4j-h8q3"}],"prev":{"headline":"Security feature bypass in Red Hat Enterprise Linux 10","id":"CVE-2026-19685"},"products":["extract-zip"],"published":"2026-08-17","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-27","vendors":["max-mapper"]},"summary":"Attackers can write arbitrary files outside the destination directory by exploiting symlink handling in extract-zip, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2026-19693/"}
