SurrealDB from 3.0.0 before 3.3.0 contains an authorization bypass vulnerability that allows authenticated record users to read records in other namespaces or databases by resolving record ids through FETCH. Attackers can switch to a foreign namespace/database and name a known record id in a RETURN … FETCH query to read another tenant's data when table PERMISSIONS allow reads.
