{"cve":"CVE-2026-107382","nvd":{"published":"2026-10-08T19:17:00.590","modified":"2026-10-08T20:25:00.647","status":"Awaiting Analysis","description":"MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. From 3.3.0 until 3.5.4, the zero-configuration TLS fingerprint-validation path calls Ed25519PasswordAuth.hash() through Authentication.validateFingerPrint, but Ed25519PasswordAuth.hash() references a seed identifier that is not in scope. Exposure requires a MariaDB server reached over TCP, TLS enabled with ssl: true or an ssl object whose rejectUnauthorized value is not false, a password set, no ssl.ca configured, and client_ed25519 negotiated as the authentication plugin. Under those conditions, a legitimate server, malicious server, or network attacker presenting a self-signed certificate can reach this path and cause a synchronous ReferenceError to escape the socket data handler. Under Node.js default uncaught-exception behavior, the client process terminates, causing denial of service. Configurations using a provided CA, rejectUnauthorized: false, another authentication plugin, or a Unix socket do not reach this vulnerable path. This issue is fixed in version 3.5.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9},"cwes":["CWE-248"],"references":["https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/784ca3d757194a05f202d84b0c762321e76a7915","https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.5.4","https://github.com/mariadb-corporation/mariadb-connector-nodejs/security/advisories/GHSA-cx2f-j9fh-8g68","https://hackerone.com/reports/3835450","https://jira.mariadb.org/browse/CONJS-356"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107382","score":0.00235,"percentile":0.14359,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-cx2f-j9fh-8g68","url":"https://osv.dev/vulnerability/GHSA-cx2f-j9fh-8g68","summary":"MariaDB Connector/Node.js: Uncaught exception crashes the client during ed25519 authentication with zero-configuration TLS","modified":"2026-10-16T09:56:02.258409116Z","packages":[{"ecosystem":"npm","name":"mariadb","purl":"pkg:npm/mariadb","ranges":[">=3.3.0 <3.5.4"],"fixed":["3.5.4"]}]}],"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).
