ANALYZED

This CVE record has been analyzed and enriched by NVDAPI.com as an independent party.

Description

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.

Remediation Upgrade: 3.3.0moderate effort Workaround:moderate effort On shared instances, use separate deployments instead of namespace/database boundaries to isolate tenants. Until you upgrade, issue namespace-, database-, and record-level credentials only to parties trusted with every tenant on the instance. Mitigation:moderate effort Prefer a PERMISSIONS WHERE clause that checks the caller's identity, such as $auth or a token claim, over PERMISSIONS FULL. This reduces exposure but does not restore the boundary.
