Summary

SurrealDB has Denial of Service in JSON parser due to nested objects

Details

The SurrealDB value and JSON parser did not enforce the configured recursion depth limit when parsing nested {, [, or ( tokens. The expression parser already enforced the limit for these tokens; the value/JSON parser omitted it. An unauthenticated attacker could send a deeply nested JSON payload to the WebSocket /rpc endpoint and exhaust server memory, crashing the process.

This is an incomplete fix for GHSA-6r8p-hpg7-825g, which addressed the same class of bug in the expression parser but did not cover the value/JSON parser code path.

Impact

An unauthenticated remote attacker can crash a SurrealDB server with a single WebSocket message. No credentials or query execution privileges are required.

Patches

A patch enforces the configured recursion depth limit in parse_value and parse_json, bringing them in line with the rest of the parser.

Versions 3.1.0 and later are not affected by this issue.

Workarounds

Restrict network access to the WebSocket /rpc endpoint to trusted clients.
