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":"2026-10-08T18:24:10.031+00:00","modifiedAt":"2026-10-08T18:42:37.155+00:00","affected":[{"ecosystem":"Vendor product","name":"mariadb-connector-nodejs","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"mariadb-corporation\",\n                    \"product\": \"mariadb-connector-nodejs\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 3.3.0, < 3.5.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"MEDIUM"}],"references":["https://github.com/mariadb-corporation/mariadb-connector-nodejs/security/advisories/GHSA-cx2f-j9fh-8g68","https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/784ca3d757194a05f202d84b0c762321e76a7915","https://hackerone.com/reports/3835450","https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.5.4","https://jira.mariadb.org/browse/CONJS-356"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107382","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107382","identifiers":["CVE-2026-107382"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
