Original NVD Description

SurrealDB versions before 3.1.5 contain a denial of service vulnerability where authenticated users can crash the server with queries containing long chains of operators. Attackers can submit queries with tens of thousands of chained operators that create unbounded expression trees, causing stack overflow during query processing and aborting the entire process.
