Default table permissions in SurrealDB were FULL instead of NONE. This would lead to tables having FULL permissions for SELECT, CREATE, UPDATE and DELETE unless some other permissions were specified via the PERMISSIONS clause. We have decided to treat this behaviour as a vulnerability due to its security implications, especially considering the lack of specific documentation and potential for confusion due to the INFO FOR DB statement previously not displaying default permissions. Treating it as a bug fix provides justification for a change in default behavior outside of a major release. Impact Any client authorized to query data in a SurrealDB instance will have full access to any tables that were defined with no explicit permissions and that are within its authorization scope (i.e. namespace or database), including creating, reading, updating and deleting data. This is specially relevant for SurrealDB instances allowing guest access with publicly exposed interfaces (e.g. HTTP REST API or WebSocket API), since a remote unauthenticated user may gain full access to any tables that were defined without any explicit permissions. Tables that were defined with explicit permissions using the PERMISSIONS clause are not affected. Patches Version 1.0.1 includes a patch for this specific issue. Later releases will also include the patch. Version 1.1.0-beta.1 and latest nightly releases already include the patch for this issue. In patched versions: Tables defined after the patch…Read More
