{"cve":"CVE-2023-34109","nvd":{"published":"2023-06-07T18:15:09.903","modified":"2026-06-17T06:02:54.837","status":"Modified","description":"zxcvbn-ts is an open source password strength estimator written in typescript. This vulnerability affects users running on the nodeJS platform which are using the second argument of the zxcvbn function. It can result in an unbounded resource consumption as the user inputs array is extended with every function call. Browsers are impacted, too but a single user need to do a lot of input changes so that it affects the browser, while the node process gets the inputs of every user of a platform and can be killed that way. This problem has been patched in version 3.0.2. Users are advised to upgrade. Users unable to upgrade should stop using the second argument of the zxcvbn function and use the zxcvbnOptions.setOptions function.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400"],"references":["https://github.com/zxcvbn-ts/zxcvbn/commit/3f9bed21b5d01f6f6863476822ca857355fba22f","https://github.com/zxcvbn-ts/zxcvbn/security/advisories/GHSA-38hx-x5hq-5fg4","https://github.com/zxcvbn-ts/zxcvbn/commit/3f9bed21b5d01f6f6863476822ca857355fba22f","https://github.com/zxcvbn-ts/zxcvbn/security/advisories/GHSA-38hx-x5hq-5fg4"],"products":["zxcvbn-ts_project:zxcvbn-ts"],"source":"nvd","synced_at":"2026-10-19T21:38:24.161619714+00:00"},"epss":{"cve":"CVE-2023-34109","score":0.00496,"percentile":0.42592,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
