GHSA-vjjx-rfw4-rmfc: SurrealDB: Graph traversal bypasses table SELECT permissions

An authenticated record or scope user could read records on any table reachable through a graph edge or REFERENCES TO back-reference, regardless of that table’s PERMISSIONS FOR select clause.

Traversing SELECT * FROM source->edge->target returned full documents from target even when target was defined as PERMISSIONS FOR select NONE. The same bypass extended through multi-hop chains, so any table reachable by a sequence of edges from a readable starting point was exposed.

The root cause: GraphEdgeScan and ReferenceScan fetched records straight from storage without routing them through Document::pluck_select, so the target table’s permission expression was never consulted.
