{"cve":"CVE-2026-107383","nvd":{"published":"2026-10-08T19:17:00.783","modified":"2026-10-14T02:16:56.777","status":"Awaiting Analysis","description":"MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to 3.2.5, 3.3.4, 3.4.7, and 3.5.4, the GeoJSON Polygon and MultiPolygon binary encoders size a Buffer.allocUnsafe() allocation from each ring's numeric length before confirming that the ring is an array. A malformed non-array ring can therefore reserve bytes that the writing loop skips, and the connector sends the full buffer through execute() or batch(), disclosing uninitialized Node.js heap data into a database value. The persisted data can include other users' content, session material, database credentials, or TLS key material and may propagate to backups and replicas. The text-protocol query() path is not affected. This issue is fixed in versions 3.2.5, 3.3.4, 3.4.7, and 3.5.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200"],"references":["https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/2314c03b785db482599d2befd06f4992e5fc46b3","https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/a4aa048b57dc47309b80e5cc25a4a8eedb32fd9f","https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/b2ca628864b0fc2e3e94ea96910f6b693ad5bd30","https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/faa27d1b2b7753a54000f586d5148089b60d1284","https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.2.5"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107383","score":0.00388,"percentile":0.32679,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-48qf-xh34-q73r","url":"https://osv.dev/vulnerability/GHSA-48qf-xh34-q73r","summary":"MariaDB Connector/Node.js exposes uninitialized process memory through malformed GeoJSON parameters","modified":"2026-10-16T09:55:42.823324858Z","packages":[{"ecosystem":"npm","name":"mariadb","purl":"pkg:npm/mariadb","ranges":["<3.2.5"],"fixed":["3.2.5"]},{"ecosystem":"npm","name":"mariadb","purl":"pkg:npm/mariadb","ranges":[">=3.3.0 <3.3.4"],"fixed":["3.3.4"]},{"ecosystem":"npm","name":"mariadb","purl":"pkg:npm/mariadb","ranges":[">=3.4.0 <3.4.7"],"fixed":["3.4.7"]},{"ecosystem":"npm","name":"mariadb","purl":"pkg:npm/mariadb","ranges":[">=3.5.0-rc.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).
