Duplicate Advisory: Untrusted Query Object Evaluation in RPC API

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-64f8-pjgr-9wmr. This link is maintained to preserve external references. ## Original Description SurrealDB before 1.5.5 (and 2.0.0-beta before 2.0.0-beta.3) accepts an arbitrary object in the signin and signup operations of the RPC API without recursively validating it for non-computed values. When a record access method defines a SIGNIN or SIGNUP query and the RPC API is exposed to untrusted users, an unauthenticated attacker can encode a binary object containing a subquery using the bincode serialization format and supply it in place of credentials. The subquery is then executed within the database owner's SIGNIN/SIGNUP query under a system user session with the editor role, allowing the attacker to select, create, update, and delete non-IAM resources (though not view the query results directly, and not affect IAM resources, which require the owner role).
