ETK-2026-3382Zero's internal tracking ID, independent of the CVE number.
validatedZero produced an exploit or a check.description
SurrealDB versions before 4.0.0 do not apply configured WebSocket size and buffer limits to the GraphQL WebSocket endpoint. An unauthenticated network client can consume server memory and degrade availability by opening GraphQL WebSocket connections when GraphQL is enabled for a database.
mitigation
Upgrade SurrealDB to version 4.0.0. Until upgrading, disable the GraphQL HTTP endpoint or block access to its WebSocket route at a reverse proxy.
fixed in 4.0.0
outcome
Check only, differential: the check fires on the vulnerable build and is silent on the patched one.
