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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"mariadb-corporation","product":"mariadb-connector-nodejs","versions":[{"version":"< 3.2.5","status":"affected"},{"version":">= 3.3.0, < 3.3.4","status":"affected"},{"version":">= 3.4.0, < 3.4.7","status":"affected"},{"version":">= 3.5.0-rc.0, < 3.5.4","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-14T01:11:14.366453Z","id":"CVE-2026-107383","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-200"}]}],"references":[{"url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/2314c03b785db482599d2befd06f4992e5fc46b3","source":"security-advisories@github.com"},{"url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/a4aa048b57dc47309b80e5cc25a4a8eedb32fd9f","source":"security-advisories@github.com"},{"url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/b2ca628864b0fc2e3e94ea96910f6b693ad5bd30","source":"security-advisories@github.com"},{"url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/commit/faa27d1b2b7753a54000f586d5148089b60d1284","source":"security-advisories@github.com"},{"url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.2.5","source":"security-advisories@github.com"},{"url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.3.4","source":"security-advisories@github.com"},{"url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.4.7","source":"security-advisories@github.com"},{"url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/releases/tag/3.5.4","source":"security-advisories@github.com"},{"url":"https://github.com/mariadb-corporation/mariadb-connector-nodejs/security/advisories/GHSA-48qf-xh34-q73r","source":"security-advisories@github.com"},{"url":"https://jira.mariadb.org/browse/CONJS-367","source":"security-advisories@github.com"}]}
