Security Vulnerabilities
SurrealDB versions before 3.1.0 contain an authentication bypass vulnerability in LIVE SELECT subscriptions where permission expressions referencing $value, $before, $after, or $event are evaluated against attacker-controlled bindings instead of actual documents. Authenticated subscribers can bind chosen values to these parameter names and register LIVE SELECT queries to receive notifications for records that SELECT permission expressions should have hidden.

SurrealDB versions before 3.1.0 fail to apply the SURREAL_WEBSOCKET_MAX_MESSAGE_SIZE limit to anonymous /sql WebSocket connections, allowing attackers to buffer unbounded frames in the per-connection read buffer. Attackers can stream WebSocket frames larger than the configured limit across multiple concurrent connections to consume excessive memory and degrade /sql availability.

SurrealDB versions before 3.1.0 contain a field-level permission bypass vulnerability in JSON Patch operations that allows authenticated users to read protected fields. Attackers can use UPDATE PATCH with an empty from pointer in copy or move operations to duplicate all record fields, including those restricted by field-level SELECT permissions, into attacker-chosen destination fields.

SurrealDB versions 3.1.0 before 3.1.5 fail to enforce field-level SELECT permissions when records are accessed through graph-edge or back-reference traversals. Attackers with table-level SELECT access can read field values hidden by field-level permissions by materializing records through graph traversals instead of direct table scans.

SurrealDB before 3.1.5 contains an arbitrary file read vulnerability in the DEFINE ANALYZER mapper filter that allows database users with EDITOR or OWNER roles to read files accessible to the SurrealDB process. Attackers can specify arbitrary file paths in the mapper filter and retrieve file contents through query error messages when the SURREAL_FILE_ALLOWLIST is empty or not configured.

SurrealDB versions before 3.1.4 fail to properly enforce SELECT permissions on array elements (field.*) for record users, leaking denied array elements instead of hiding them. Attackers with record scope access can read array elements that element-level permissions should deny by exploiting incorrect index handling during permission filtering.

SurrealDB versions before 3.1.0 fail to validate DEFINE NAMESPACE or DEFINE DATABASE permissions when processing USE NS and USE DB statements. Unauthenticated attackers can create arbitrary namespaces and databases by issuing USE commands, bypassing authorization checks in the RPC use method and SurrealQL executor.

SurrealDB versions before 3.1.0 contain a field-level SELECT permission bypass vulnerability in indexed COUNT fast paths. Attackers can execute COUNT queries on indexed fields with field-level SELECT restrictions to confirm or recover restricted field values through repeated guesses.

SurrealDB before 3.1.0 contains a capability bypass vulnerability in HTTP redirect handling that allows authenticated users to circumvent port-scoped --deny-net rules. Attackers can chain an HTTP redirect from an allowed hostname to a denied host:port combination, and the redirect is followed because the port information is dropped during redirect policy evaluation.

SurrealDB before 3.1.5 contains a server-side request forgery vulnerability in the JWKS fetcher that follows HTTP redirects without re-validating redirect targets against network capabilities. Attackers with Owner role can configure a JWKS URL pointing to an allowlisted host that redirects to blocked internal addresses, bypassing network access controls.
