CVE-2026-63749

SurrealDB before 3.1.0 contains an authentication bypass in LIVE SELECT subscriptions. In these subscriptions, permission expressions referencing $value, $before, $after, or $event are evaluated against attacker-controlled bindings rather than the actual documents. An authenticated subscriber can...

CVE-2026-63747

SurrealDB prior to 3.1.0 contains a denial-of-service condition in the RPC use handler. When a request sets db without a namespace, a malformed WebSocket message sent to the /rpc endpoint can cause the server process to panic, leading to service disruption. The issue is exploitable by unauthentic...

CVE-2026-63748

SurrealDB before 3.1.0 contains an information disclosure vulnerability: authenticated users with UPDATE access can read field values hidden by field-level SELECT permissions via error messages. Attackers can trigger arithmetic/extend operations on hidden fields to embed raw operand values in res...

CVE-2026-63746 SurrealDB before 3.1.0 Permission Bypass via Graph Traversal

SurrealDB versions before 3.1.0 fail to enforce table SELECT permissions when traversing graph edges or back-references. Authenticated users can read records from any table reachable through graph edges regardless of the target table's PERMISSIONS FOR select clause...

CVE-2026-63746

SurrealDB is affected in versions before 3.1.0 where SELECT permissions are not enforced during graph traversal and traversal of back-references. The root cause is failure to apply PERMISSIONS FOR select on target tables when navigating graph edges, allowing authenticated users to read records fr...
