CVE-2026-9752

An authorized user could trigger a server crash by running a query with a 2dsphere index on a field that stores a GeoJSON GeometryCollection containing a Polygon with a strict-winding CRS. Strict-winding polygons are intentionally unsupported for indexing, but the guard that rejects them does not inspect members of a GeometryCollection, allowing the unsafe path to be reached which ends with an ensuing null-pointer dereference.

Summary		(es) Un usuario autorizado podría provocar una caída del servidor al ejecutar una consulta con un índice 2dsphere en un campo que almacena una colección de geometrías GeoJSON que contiene un polígono con un CRS de bobinado estricto. Los polígonos de bobinado estricto no son compatibles intencionadamente para la indexación, pero la protección que los rechaza no inspecciona los miembros de una colección de geometrías, lo que permite alcanzar la ruta insegura que termina con una posterior desreferenciación de puntero nulo.
