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.","state":0,"publishedAt":"2026-10-08T19:17:00.59+00:00","modifiedAt":"2026-10-08T20:25:00.647+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9,"severity":"MEDIUM"}],"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"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-107382","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-248"],"productCriteria":[],"sourceDates":{"published":"2026-10-08T19:17:00.590","lastModified":"2026-10-08T20:25:00.647"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
