CVE-2026-63758 Details
Description
SurrealDB versions before 3.1.0 contain an authorization bypass vulnerability in the KILL statement that allows authenticated database users to terminate other users' LIVE SELECT subscriptions. Attackers can issue KILL statements with target live query UUIDs to disrupt real-time data subscriptions of other users without ownership verification.
A vulnerability exists in SurrealDB versions prior to 3.1.0, allowing authenticated users with database-level access to bypass authorization in the KILL statement. This vulnerability enables users to terminate other users' LIVE SELECT subscriptions, disrupting real-time data updates without ownership verification. The KILL statement can be exploited by issuing commands with the UUIDs of target live queries, causing a silent interruption of the affected users' data subscriptions.
Users can upgrade to SurrealDB version 3.1.0 or later, where this vulnerability has been patched. For those unable to upgrade, it is recommended to treat live query UUIDs as sensitive information to prevent exposure through application logs or shared interfaces. In critical multi-tenant environments, consider using separate databases for each tenant instead of relying on record-level access controls within a shared database.
