description

SurrealDB versions before 3.3.0 mishandle authorization when constructing HTTP sessions. An authenticated attacker may access or alter records in another tenant by causing the session to use a namespace and database different from those checked for their credentials. The attacker must have valid credentials for at least one tenant.

mitigation

Upgrade SurrealDB to version 3.3.0 or later. Until upgraded, restrict HTTP API access to trusted clients and isolate tenant access at the network boundary.

fixed in 3.3.0
