Executive Summary

SurrealDB before version 3.1.0 fails to refresh authentication state in LIVE SELECT subscriptions when session credentials are revoked or expire. This means users can continue receiving real-time notifications based on old permissions even after their access is terminated.

Detection Guidance

To detect this vulnerability, monitor SurrealDB instances running versions before 3.1.0 for unauthorized continued access via LIVE SELECT subscriptions after session changes. Check logs for persistent real-time notifications despite revoked or expired credentials. Use SurrealDB's admin interface or API to inspect active LIVE queries and their associated authentication states.

Impact Analysis

Attackers with revoked or expired session credentials can still receive real-time data notifications until the connection closes. This bypasses updated access controls, potentially exposing sensitive information.

Compliance Impact

This vulnerability may violate data access control requirements in GDPR and HIPAA by allowing unauthorized continued access to sensitive data after session termination.

Mitigation Strategies

Upgrade SurrealDB to version 3.1.0 or later to patch the vulnerability. If upgrading is not possible, manually reset LIVE queries before session changes or restrict session durations to minimize exposure. Monitor and invalidate active LIVE subscriptions after session revocations or expirations.
