Summary
SurrealDB from 3.0.0 before 3.3.0 has a missing authorization check (CWE-862) that lets an authenticated record user read records in other namespaces or databases. An attacker switches to a foreign namespace or database and names a known record id in a RETURN … FETCH query, which reads another tenant's data when the table PERMISSIONS allow reads. The attacker needs valid credentials for a record user but no elevated privileges, and the CVSS 4.0 vector rates the impact to confidentiality as high.

Description from the CNA
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.
