+  "details": "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.\n\nTraversing `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.\n\nThe 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.\n\n### Impact\n\nAn authenticated record or scope user can read records on any table reachable through a chain of graph edges or back-references from a table they have `select` on, regardless of the target's `PERMISSIONS FOR select` clause. Confidentiality-only and bounded to the caller's current database — namespace and database isolation are unaffected.\n\n### Patches\n\nA new per-batch permission cache (`exec::permission::CachedTableSelect`) resolves each target table's `SELECT` permission once and filters yielded values through `check_permission_for_value`, matching the regular `SELECT` code path.\n\n- Versions 3.1.0 and later are not affected.\n\n### Workarounds\n\n- Remove `select` permission on edge tables whose targets should be hidden.\n- Use namespace or database isolation as the primary boundary where feasible.",
