CVE-2026-63738Network attack vector

Restricted-field disclosure via unfiltered graph traversal

Published Jul 20, 2026 · Updated Jul 20, 2026

Incorrect authorization in SurrealDB 3.1.0 through 3.1.4 allows remote authenticated users to read restricted fields via graph traversals. The shared resolve_record_batch helper for GraphEdgeScan and ReferenceScan materializes raw records after table-level checks without applying field-level SELECT filters. Table-level SELECT access is required, and disclosure is limited to hidden fields in otherwise readable records; row, table, namespace, and database boundaries remain enforced.
