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":"2026-10-08T18:27:02.543+00:00","modifiedAt":"2026-10-14T01:11:23.281+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\": \"< 3.2.5\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.3.0, < 3.3.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.4.0, < 3.4.7\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.5.0-rc.0, < 3.5.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://github.com/mariadb-corporation/mariadb-connector-nodejs/security/advisories/GHSA-48qf-xh34-q73r","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://jira.mariadb.org/browse/CONJS-367"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107383","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107383","identifiers":["CVE-2026-107383"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
