CVE-2026-63734 PUBLISHED

SurrealDB before 3.2.0 Denial of Service via malformed SurrealML import

Assigner: VulnCheck
Reserved: 18.07.2026 Published: 20.07.2026 Updated: 20.07.2026

SurrealDB versions before 3.2.0 contain a denial of service vulnerability in the SurrealML header parser that allows authenticated Owner-role users to crash the server by uploading a malformed .surml file to the /ml/import endpoint. Attackers can supply non-numeric input-dimensions or other malformed header fields that trigger unchecked unwrap calls, causing a panic that aborts the entire server process and denies service to all databases.
