📋 Description

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-q729-696q-g9pq. This link is maintained to preserve external references.

Original 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.
