SurrealDB is a scalable, distributed, collaborative, document-graph database for the realtime web. Prior to 3.1.0, Document::purge_edges in surrealdb/core/src/doc/delete.rs automatically removed graph edge records with permissions disabled through opt.clone().with_perms(false) when a connected node was deleted, bypassing the edge table's PERMISSIONS FOR delete and PERMISSIONS FOR select clauses. This issue is fixed in version 3.1.0.
