CVE ID :CVE-2026-9752
Published : June 9, 2026, 10:27 p.m. | 37 minutes ago
Description :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.
Severity: 7.1 | HIGH
