{"id":"CVE-2026-119280","aliases":["GHSA-4jq2-8v3c-97w8"],"title":"MariaDB Connector/J : XA recover() trusted server-supplied gtrid and bqual lengths","titleSource":"GitHub_M","descriptionSource":"OSV","declaredSeverity":"LOW","description":"## Summary\n\n`XAResource.recover()` in MariaDB Connector/J trusted the `gtrid_length` and\n`bqual_length` columns returned by `XA RECOVER` to allocate and split each Xid.\n\n## Details\n\n`MariaDbPoolConnection` and `MariaDbPoolPinnedConnection` built each `Xid` of\nthe recovery list by allocating `new byte[gtrid_length]` and\n`new byte[bqual_length]` and copying from the `data` column, without validating\nthe lengths against the XA specification bounds (`Xid.MAXGTRIDSIZE`,\n`Xid.MAXBQUALSIZE`) or the actual payload. Negative or oversized lengths, or\nlengths that do not fit the data, ended in large allocations or unchecked\nexceptions (`NegativeArraySizeException`, `ArrayIndexOutOfBoundsException`)\nduring recovery.\n\nThe fix validates the lengths before any allocation or copy and reports an\ninvalid row as an `XAException` (`XAER_RMFAIL`).\n\n## Impact\n\nAvailability only, and limited to applications running XA recovery: a malicious\nor compromised server, or a MitM, can crash the recovery or drive large\nallocations. Exploitation requires control of the server side of the connection.\n\n## Credit\n\nReported by
