CVE-2026-63735SurrealDB versions before 3.2.0 fail to validate namespace and database scope in custom API routes, allowing authenticated users to invoke endpoints in different namespaces/databases. Attackers with valid credentials for any namespace/database can access custom API endpoints in other tenants by specifying the target scope in the URL path, reading sensitive data or triggering unintended operations.Surrealdb High CVSS 8.1 CVE-2026-63739SurrealDB 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 High CVSS 7.7 CVE-2026-63747SurrealDB versions before 3.1.0 contain a denial of service vulnerability in the RPC use handler that panics when db is set without a namespace. Unauthenticated attackers can send a malformed WebSocket message to the /rpc endpoint to crash the server process.Surrealdb High CVSS 7.5 CVE-2026-63750SurrealDB 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 High CVSS 7.5 CVE-2026-63756SurrealDB versions before 3.1.0 contain a time-of-check/time-of-use race condition in the HTTP /rpc endpoint that allows unauthenticated requests to inherit authenticated session state. Unauthenticated attackers can send concurrent requests to the /rpc endpoint while legitimate authenticated traffic is active to execute operations with hijacked user privileges.Surrealdb High CVSS 8.1 CVE-2026-63757SurrealDB versions before 3.1.0 contain a session hijacking vulnerability where the HTTP /rpc sessions method returns attached session UUIDs without authentication and accepts arbitrary session fields with no ownership verification. Unauthenticated attackers can enumerate session UUIDs and impersonate authenticated sessions to read, write, delete data and escalate privileges.Surrealdb High CVSS 8.8 CVE-2026-63760SurrealDB before 3.1.0 fails to enforce the configured recursion depth limit in the value and JSON parser when processing nested braces, brackets, or parentheses. Unauthenticated attackers can send deeply nested JSON payloads to the WebSocket /rpc endpoint to exhaust server memory and crash the process.Surrealdb High CVSS 7.5 CVE-2026-63763SurrealDB before 2.5.0 and before 3.0.0-beta.3 contains a confused deputy privilege escalation vulnerability. Unprivileged users (e.g., those with the database editor role) can create or modify fields containing futures, functions, or closures. Because these are executed in the context of the invoking/querying user rather than their creator, an attacker can plant malicious logic that executes with a higher-privileged user's permissions when that user reads or writes the affected record. This can lead to full privilege escalation, including creation of a root owner and server takeover.Surrealdb High CVSS 8.8 CVE-2023-54366SurrealDB before 1.0.1 sets default table permissions to FULL instead of NONE, allowing SELECT, CREATE, UPDATE, and DELETE operations on tables without explicit permissions. Attackers with database access or unauthenticated users on publicly exposed instances can perform unrestricted operations on unprotected tables within their authorization scope.Surrealdb High CVSS 8.8 CVE-2024-58362SurrealDB before 1.5.5 (and 2.0.0-beta before 2.0.0-beta.3) accepts an arbitrary object in the signin and signup operations of the RPC API without recursively validating it for non-computed values. When a record access method defines a SIGNIN or SIGNUP query and the RPC API is exposed to untrusted users, an unauthenticated attacker can encode a binary object containing a subquery using the bincode serialization format and supply it in place of credentials. The subquery is then executed within the database owner's SIGNIN/SIGNUP query under a system user session with the editor role, allowing the attacker to select, create, update, and delete non-IAM resources (though not view the query results directly, and not affect IAM resources, which require the owner role).Surrealdb High CVSS 8.8 CVE-2024-58368SurrealDB versions before 1.1.0 fail to properly parse the ID, DB, and NS headers in HTTP REST API requests containing special characters. Unauthenticated attackers can send crafted HTTP requests with malformed header values to trigger an uncaught exception that crashes the server.Surrealdb High CVSS 7.5 CVE-2025-71390SurrealDB before 2.2.6, 2.3.6, and 2.1.8 (and 3.0.0-alpha.7 and earlier) fails to validate DNS-resolved hostnames against --deny-net network access restrictions in its http::* functions. An authenticated user can invoke http::<fn>(<url>) with a hostname that resolves to a denied IP address, causing the server to issue the request anyway and return the response. This bypasses network access controls, allowing access to restricted internal endpoints and potentially retrieving or altering sensitive information and credentials, depending on the deployment.Surrealdb High CVSS 8.8 CVE-2025-71392SurrealDB before 2.0.5, 2.1.x before 2.1.5, and 2.2.x before 2.2.2 fails to properly escape table and field names in the command-line export command. An authenticated System User with OWNER or EDITOR roles can create tables or fields with malicious names containing SurrealQL. When a higher-privileged user subsequently imports the exported backup, the injected SurrealQL executes, enabling privilege escalation and root-level takeover of the SurrealDB instance. Applications that let users define custom tables or fields are also exposed to a universal second-order SurrealQL injection even when query parameters are sanitized.Surrealdb Critical CVSS 9.4
