In Apache Derby 10.1.2.1, 10.2.2.0, 10.3.1.4, and 10.4.1.3, Export processing may allow an attacker to overwrite an existing file.

XML external entity (XXE) vulnerability in the SqlXmlUtil code in Apache Derby before 10.12.1.1, when a Java Security Manager is not in place, allows context-dependent attackers to read arbitrary files or cause a denial of service (resource consumption) via vectors involving XmlVTI and the XML datatype.

Apache Derby before 10.2.1.6 does not determine privilege requirements for lock table statements at compilation time, and consequently does not enforce privilege requirements at execution time, which allows remote authenticated users to lock arbitrary tables.

Apache Derby before 10.2.1.6 does not determine schema privilege requirements during the DropSchemaNode bind phase, which allows remote authenticated users to execute arbitrary drop schema statements in SQL authorization mode.
