Description
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.
