Versions prior to 7.2.2 crash with a memory-safety fault when it parses a GeoJSON document whose geometry contains a malformed coordinate. The coordinate parser in `adagucserverEC/CConvertGeoJSON.cpp` indexes `pt.u.array.values[0]` and `pt.u.array.values[1]` and uses `polygon.u.array.length` as a loop bound without first validating the JSON node type or the coordinate length. A coordinate that is an empty array, a one-element array, a scalar, or `null` leads to an out-of-bounds heap read or a NULL pointer dereference. The same unchecked pattern is present in four geometry branches: `Polygon`, `LineString`, `MultiLineString` and `MultiPolygon`. The vulnerable parser runs whenever the server processes a local GeoJSON file, either a configured GeoJSON dataset or a GeoJSON file exposed through the `AutoResource` feature and requested by an unauthenticated WMS request. A crafted GeoJSON file reliably crashes the backend process that handles that request. Version 7.2.2 patches the vulnerability."}], "lastModified": "2026-08-18T18:17:52.650", "sourceIdentifier": "security-advisories@github.com"}
