Updated Jul 23, 2026
MongoDB
Parameter Value
CVSS 7.1 (HIGH)
Affected Versions 7.0.0 — 8.3.3
Fixed In 7.0.35
Type CWE-476 (NULL Pointer Dereference)
Vendor MongoDB
Public PoC No

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.
