{"id":"CVE-2026-119280","published":"2026-10-29T21:17:21.553","lastModified":"2026-10-29T21:17:21.553","description":"MariaDB Connector/J is used to connect applications developed in Java to MariaDB and MySQL databases. From 3.0.0 until 3.3.7, 3.4.5, and 3.5.11, the MariaDbPoolConnection.recover() and MariaDbPoolPinnedConnection.recover() implementations trusted the gtrid_length and bqual_length columns returned by XA RECOVER. The methods allocated and split Xid byte arrays without validating the lengths against Xid.MAXGTRIDSIZE, Xid.MAXBQUALSIZE, or the actual data payload. A malicious or compromised server, or a machine-in-the-middle attacker, could cause large allocations, NegativeArraySizeException, or ArrayIndexOutOfBoundsException during XA recovery. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.11.","cvssScore":3.7,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","cwes":["CWE-20","CWE-789"],"vendors":[],"products":[],"references":[{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/280efcfb4390055858fa2dd12b722d85a6a13ab8","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/47aba5a23548b35191865a428cc674316b95ee47","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/e9d767103bfd178ed57caa4cb97bbfbf7e54da6b","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.3.7","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.4.5","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.5.11","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/security/advisories/GHSA-4jq2-8v3c-97w8","tags":[]}],"exploitRefs":[{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/280efcfb4390055858fa2dd12b722d85a6a13ab8","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/47aba5a23548b35191865a428cc674316b95ee47","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/e9d767103bfd178ed57caa4cb97bbfbf7e54da6b","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.3.7","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.4.5","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.5.11","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/security/advisories/GHSA-4jq2-8v3c-97w8","tags":[]}],"hasPoc":true,"ai":null}
