## What `ST_GeomFromGML` did not disable external entity expansion when parsing GML input, allowing XXE (XML External Entity) attacks via crafted GML strings containing `<!DOCTYPE>` declarations. ## Fix Configure the XML parser with: - `disallow-doctype-decl = true` - `external-general-entities = false` - `external-parameter-entities = false` - `load-external-dtd = false` ## Tests - Normal GML strings still parse correctly - Malicious GML with DOCTYPE + external entity is rejected - Empty/null input handled gracefully ## Jira [CALCITE-7601](https://issues.apache.org/jira/browse/CALCITE-7601) -- This is an automated message from the Apache Git Service.
