CyberRota Analysis

AI-Generated

SurrealDB versions prior to 3.1.0 are vulnerable due to inadequate enforcement of recursion depth limits in their JSON parser, allowing unauthenticated attackers to exploit this flaw. By sending deeply nested JSON payloads to the WebSocket /rpc endpoint, attackers can exhaust server memory, potentially leading to a denial of service. Organizations using SurrealDB should prioritize this vulnerability to mitigate the risk of service disruption.

Original NVD Description

SurrealDB 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.
