A PERMISSIONS ... WHERE clause is evaluated with permission enforcement disabled, so it can't recurse into its own checks. But the clause could also contain data-modifying statements, and these ran with enforcement still off — so evaluating a permission check could write to tables the caller cann...

SurrealDB: Custom API route lets authenticated callers override namespace/database scope via URL path

An authenticated user scoped to one namespace/database could invoke a custom API DEFINE API belonging to a different namespace/database, reaching another tenant's endpoint. The route /api/namespace/database/endpoint took the namespace and database from the URL and applied them to the caller's...

GHSA-M3C3-78FH-W3W7 SurrealDB allows bypass of deny-net flags via DNS resolution

SurrealDB offers http functions that can access external network endpoints. A typical, albeit not recommended configuration would be to start SurrealDB with all network connections allowed with the exception of a deny list. For example, surreal start --allow-net --deny-net 10.0.0.0/8 will allow a...
