{"id":"BIT-mariadb-2026-107383","summary":"MariaDB Connector/Node.js exposes uninitialized process memory through malformed GeoJSON parameters","details":"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.","aliases":["BIT-mariadb-min-2026-107383","BIT-mysql-client-2026-107383","CVE-2026-107383","GHSA-48qf-xh34-q73r"],"modified":"2026-10-16T09:55:42.823324858Z","published":"2026-10-16T08:41:49.993Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:mariadb:mariadb:*:*:*:*:*:node.js:*:*"]},"references":[{"type":"WEB","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/2314c03b785db482599d2befd06f4992e5fc46b3"},{"type":"WEB","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/a4aa048b57dc47309b80e5cc25a4a8eedb32fd9f"},{"type":"WEB","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/b2ca628864b0fc2e3e94ea96910f6b693ad5bd30"},{"type":"WEB","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/faa27d1b2b7753a54000f586d5148089b60d1284"},{"type":"WEB","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.2.5"},{"type":"WEB","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.3.4"},{"type":"WEB","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.4.7"},{"type":"WEB","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.5.4"},{"type":"WEB","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/security/advisories/GHSA-48qf-xh34-q73r"},{"type":"WEB","url":"https://jira.mariadb.org/browse/CONJS-367"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107383"}],"affected":[{"package":{"name":"mariadb","ecosystem":"Bitnami","purl":"pkg:bitnami/mariadb"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.2.5"},{"introduced":"3.3.0"},{"fixed":"3.3.4"},{"introduced":"3.4.0"},{"fixed":"3.4.7"},{"introduced":"3.5.0"},{"fixed":"3.5.4"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mariadb/BIT-mariadb-2026-107383.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
