Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Calcite (calcite-core, Maven) versions 1.22.0 up to but not including 1.32.0 are vulnerable to XML External Entity (XXE) attacks. The SQL operators EXISTS_NODE, EXTRACT_XML, XML_TRANSFORM and EXTRACT_VALUE do not restrict external entity references, so applications exposing them, typically through the Oracle or MySQL dialects, can be attacked. The impact depends on the privileges of the user the application runs under. Upgrade to calcite-core 1.32.0, which disables Document Type Declarations and external entity resolution on these operators.
