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-2017-14919 in the wild and no public exploit code.\n\nAffected product: Nodejs Node.js. 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-2017-14919/ (Markdown: https://insights.sbomify.com/CVE-2017-14919/index.md)","id":"CVE-2017-14919","markdown":"https://insights.sbomify.com/CVE-2017-14919/index.md","name":"CVE-2017-14919","record":{"aliases":["ALPINE-CVE-2017-14919","CLEANSTART-2026-JL30943","CLEANSTART-2026-LL47862","GHSA-mvc4-gp8c-r52f"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js runtime","requires_auth":"none","summary":"Remote attackers can crash Node.js applications by sending data that triggers an uncaught exception in the zlib module due to invalid windowBits parameters.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"node.js","vendor":"nodejs"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Node.js before 4.8.5, 6.x before 6.11.5, and 8.x before 8.8.0 allows remote attackers to cause a denial of service (uncaught exception and crash) by leveraging a change in the zlib module 1.2.9 making 8 an invalid value for the windowBits parameter.","ecosystems":[],"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":"Denial of service in n/a","id":"CVE-2017-14919","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"nodejs:node.js","products":["nodejs:node.js"],"type":"denial_of_service","year":"2017"},"n_packages":0,"n_references":5,"next":{"headline":"eGroupware Community Edition Stored XSS vulnerability","id":"CVE-2017-14920"},"packages":[],"prev":{"headline":"Use after free in Android for MSM, Firefox OS for MSM, QRD Android","id":"CVE-2017-14918"},"products":["n/a"],"published":"2017-10-30","related":[{"cvss_score":9.8,"headline":"Security feature bypass in Node","id":"CVE-2023-32002","kev_date_added":null,"published":"2023-08-21"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2016-6303","kev_date_added":null,"published":"2016-09-16"},{"cvss_score":9.1,"headline":"Security feature bypass in Node.js","id":"CVE-2017-15896","kev_date_added":null,"published":"2017-12-11"},{"cvss_score":8.8,"headline":"Server-side request forgery in Node.js","id":"CVE-2018-7160","kev_date_added":null,"published":"2018-05-17"},{"cvss_score":8.1,"headline":"Misconfiguration in Node.js","id":"CVE-2018-12120","kev_date_added":null,"published":"2018-11-28"},{"cvss_score":7.9,"headline":"Path traversal in Node","id":"CVE-2024-21891","kev_date_added":null,"published":"2024-02-20"},{"cvss_score":7.9,"headline":"Path traversal in Node","id":"CVE-2024-21896","kev_date_added":null,"published":"2024-02-20"}],"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":"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":"2026-07-14","vendors":["n/a"]},"summary":"Remote attackers can crash Node.js applications by sending data that triggers an uncaught exception in the zlib module due to invalid windowBits parameters.","url":"https://insights.sbomify.com/CVE-2017-14919/"}
