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.","state":0,"publishedAt":"2026-10-08T19:17:00.783+00:00","modifiedAt":"2026-10-14T02:16:56.777+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"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","https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.3.4","https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.4.7","https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.5.4","https://github.com/mariadb-corporation/mariadb-connector-nodejs/security/advisories/GHSA-48qf-xh34-q73r","https://jira.mariadb.org/browse/CONJS-367"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-107383","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-200"],"productCriteria":[],"sourceDates":{"published":"2026-10-08T19:17:00.783","lastModified":"2026-10-14T02:16:56.777"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
