{"id":"CVE-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":["GHSA-48qf-xh34-q73r"],"modified":"2026-10-10T02:47:27.627213256Z","published":"2026-10-08T18:27:02.543Z","database_specific":{"cwe_ids":["CWE-200"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107383.json","cna_assigner":"GitHub_M"},"references":[{"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://jira.mariadb.org/browse/CONJS-367"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107383.json"},{"type":"ADVISORY","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/security/advisories/GHSA-48qf-xh34-q73r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107383"},{"type":"FIX","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/2314c03b785db482599d2befd06f4992e5fc46b3"},{"type":"FIX","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/a4aa048b57dc47309b80e5cc25a4a8eedb32fd9f"},{"type":"FIX","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/b2ca628864b0fc2e3e94ea96910f6b693ad5bd30"},{"type":"FIX","url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/faa27d1b2b7753a54000f586d5148089b60d1284"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mariadb-corporation/mariadb-connector-nodejs","events":[{"introduced":"0"},{"introduced":"b65aca10b77f5ede83f16a8edd0537b2ef12a16f"},{"introduced":"24a58245cba201da91f41f7f96f8dd165d31c6c7"},{"introduced":"07d0183bbcf61a9cd9a5b39a74a67d676e83b4d8"},{"fixed":"d7c1aed221af4bf811e7d13f3e29c2f7484bb0e0"},{"fixed":"ee9b296894d0c9bcc0e0f6b9ac9316f498eecec4"},{"fixed":"67c931b7407fc4e460aab020e7cb53bcb1c62e50"},{"fixed":"ff43a2c80ebba9e6590afd6b9cc08ac0a290892a"},{"fixed":"2314c03b785db482599d2befd06f4992e5fc46b3"},{"fixed":"a4aa048b57dc47309b80e5cc25a4a8eedb32fd9f"},{"fixed":"b2ca628864b0fc2e3e94ea96910f6b693ad5bd30"},{"fixed":"faa27d1b2b7753a54000f586d5148089b60d1284"}],"database_specific":{"extracted_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-rc.0"},{"fixed":"3.5.4"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["3.2.4","3.3.3","3.4.6","3.5.2","3.5.1","3.4.5","3.5.0-rc.0","3.4.4","3.4.3","3.3.2","3.4.2","3.4.1","3.2.3","3.4.0","3.3.1","3.3.0","3.2.2","3.2.1","3.2.0","3.0.0-ga","2.5.6","2.5.4","2.5.3","2.5.2","2.5.1","2.5.0","2.4.2","2.4.1","2.4.0","2.3.0","2.2.0","2.1.5","2.1.4","2.1.3","2.1.2","2.1.1","2.1.0","2.0.5","2.0.3","0.7.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-107383.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
