Vulnerability Title
SurrealDB before 3.1.0 RELATE Statement Record Overwrite
Source: CVE Program / CVE List V5
Vulnerability Description
SurrealDB before 3.1.0 contains an authorization bypass vulnerability in the RELATE statement that allows authenticated users with CREATE permission to overwrite existing edge records without UPDATE permission. Attackers can issue a RELATE statement with a SET id clause pointing to an existing edge id, causing the storage layer to silently overwrite the target record instead of rejecting the operation.
