SurrealDB versions before 3.1.0 contain a denial of service vulnerability in the RPC use handler that panics when db is set without a namespace. Unauthenticated attackers can send a malformed WebSocket message to the /rpc endpoint to crash the server process.
AnalysisAI
Denial of service in SurrealDB before 3.1.0 lets an unauthenticated remote attacker crash the entire database process with a single WebSocket message to the /rpc endpoint. Sending an RPC 'use' call that sets a database (db) without first selecting a namespace triggers a Rust panic on an .expect() call; because surrealdb-core is compiled with panic = 'abort', the panic aborts the whole process rather than the connection. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker only needs network reachability to the WebSocket /rpc endpoint and must send an RPC 'use' call that sets the 'db' field while no namespace ('ns') has been selected on the session. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely high-priority DoS. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who can reach a SurrealDB server's /rpc WebSocket endpoint opens a connection and, without authenticating, sends a single RPC 'use' message setting db to any value while omitting the namespace (e.g. use { db: "x" }). … |
| Remediation | Vendor-released patch: upgrade to SurrealDB 3.1.0 or later, which replaces the panic with a typed 'invalid_params' error response when db is set on a session that has no ns (fix commit https://github.com/surrealdb/surrealdb/commit/1537ec4fbd789c61a5b43b648a854577dbe31a34; advisory https://github.com/surrealdb/surrealdb/security/advisories/GHSA-wjjj-24cx-f28g). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all SurrealDB deployments running versions before 3.1.0 and assess whether the /rpc endpoint is accessible from untrusted networks. …
