CVE-2026-109337 Details

ANALYZED

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

Description

SurrealDB before 3.3.0 contains an authorization bypass vulnerability that allows record users to infer field values hidden by field-level SELECT permissions using LIVE SELECT WHERE predicates over $before or $after. Attackers can craft repeated predicates and observe whether notifications are delivered on CREATE, UPDATE, or DELETE to confirm or narrow restricted field values.

Remediation Upgrade: 3.3.0moderate effort Workaround:low effort Do not rely on field-level SELECT permissions to hide values on a table that untrusted users can subscribe to; keep sensitive fields in a separate table or database those users cannot read at all, or restrict at the table level. Mitigation:low effort Deny live and arbitrary queries to untrusted principal classes with --deny-arbitrary-query (env SURREAL_CAPS_DENY_ARBITRARY_QUERY), for example for guest and record, which also blocks the LIVE RPC for those classes.
