{"id":"CVE-2026-119277","published":"2026-10-29T21:17:21.067","lastModified":"2026-10-29T21:17:21.067","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, decoders for OK packet session-state blocks, column definition packets, text row data, or binary row data used server-declared lengths without confirming that the requested bytes remained in the receive buffer. The decoders could position reads, create sub-buffers, or decode strings beyond the packet boundary. A malicious or compromised server, or a machine-in-the-middle attacker, could trigger unchecked ArrayIndexOutOfBoundsException or IllegalArgumentException failures inside JDBC calls and terminate connection handling. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.11.","cvssScore":5.9,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-125","CWE-130"],"vendors":[],"products":[],"references":[{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/49c92adfcf816853e324031ba9762a69444cfd12","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/52538206298db39062ad67939f1446b767cacde4","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/ea8c7b6537e50053444188a9a3fd9cae99550f56","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-wfxr-v78w-p49r","tags":[]}],"exploitRefs":[{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/49c92adfcf816853e324031ba9762a69444cfd12","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/52538206298db39062ad67939f1446b767cacde4","tags":[]},{"url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/ea8c7b6537e50053444188a9a3fd9cae99550f56","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-wfxr-v78w-p49r","tags":[]}],"hasPoc":true,"ai":null}
