{"id":"UBUNTU-CVE-2026-119281","details":"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 connector assumed result bytes were UTF-8 but guarded only changes to character_set_client. It did not reject non-UTF-8 character_set_results changes and relied on the server's global session_track_system_variables configuration to report character-set changes. A malicious or compromised server, or a machine-in-the-middle attacker, could suppress tracking or change the result charset so application strings differed from the returned bytes, potentially defeating application-side validation or escaping that depended on the decoded values. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.11.","modified":"2026-10-31T03:30:03.258069569Z","published":"2026-10-30T00:00:00Z","upstream":["CVE-2026-119281"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119281"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119281"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/af5e565eb171cfc66ea8e948ddc616abed0c4623"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/d51b968c1b795c73d24e0b3f960205b7bc82d423"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/fdabe74a7df6dce1d6c099f4d0ca1e2acc25919a"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.3.7"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.4.5"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.5.11"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/security/advisories/GHSA-grfq-r75j-rw9x"}],"affected":[{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.0-1~18.04"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.3.0-1~18.04"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119281.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.2-1build2","2.5.3-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.5.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119281.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.2-1","2.7.4-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.7.4-1","binary_name":"libmariadb-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119281.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.6-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.7.6-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119281.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.6-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.7.6-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119281.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.6-1","2.7.6-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.7.6-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119281.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
