Lifecycle Timeline
7DescriptionCVE.org
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.
AnalysisAI
Denial of service in MongoDB Server allows an authenticated user to crash the database process by issuing a geospatial query backed by a 2dsphere index where the indexed field holds a GeoJSON GeometryCollection containing a Polygon defined with a strict-winding CRS. The flaw is a CWE-476 null pointer dereference reached because the rejection guard for unsupported strict-winding polygons does not recurse into GeometryCollection members. No public exploit identified at time of analysis and the issue is not on the CISA KEV list.
