8.7 highEPSS 0.5%

High (8.7) in surrealdb surrealdb. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in surrealdb 3.1.0.

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.
