SurrealDB 2.0.0 before 3.3.1 deny-funcs Capability Bypass via Method-Style Invocations
SurrealDB 2.0.0 before 3.3.1 does not enforce --deny-funcs restrictions on method-style function calls in the streaming engine, because MethodPart::evaluate invokes resolved functions without a capability check. Authenticated users who can submit queries can …

SurrealDB before 3.3.0 Cross-Tenant Access via USE Statement
SurrealDB before 3.3.0 allows cross-tenant access because the SurrealQL USE statement switches a session to any namespace/database without checking that the caller's authenticated level covers it. Authenticated namespace, database, or record users can switch …

SurrealDB before 3.3.0 Field Permission Bypass via PATCH copy/move/test Operations
SurrealDB before 3.3.0 contains an authorization bypass vulnerability that allows callers with table-level write permission to read SELECT-restricted fields by resolving JSON Patch pointers against the unreduced record. Attackers can use PATCH copy or move op…

SurrealDB before 3.3.0 Cross-Tenant Access via Surreal-NS/Surreal-DB Headers and RPC use
SurrealDB before 3.3.0 does not check the caller-selected namespace or database against the level at which a namespace- or database-level system user authenticated, allowing cross-tenant access. An authenticated attacker can set the Surreal-NS/Surreal-DB head…

SurrealDB before 3.3.0 Cross-Tenant Access via Headers
SurrealDB before 3.3.0 contains an authorization bypass in HTTP session construction where check_auth() verifies credentials against Surreal-Auth-NS and Surreal-Auth-DB headers but constructs sessions using Surreal-NS and Surreal-DB headers without validating…

SurrealDB before 3.1.0 Denial of Service via JSON Parser
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…

High 8.8
SurrealDB before 3.1.0 Session Hijacking via /rpc sessions
SurrealDB versions before 3.1.0 contain a session hijacking vulnerability where the HTTP /rpc sessions method returns attached session UUIDs without authentication and accepts arbitrary session fields with no ownership verification. Unauthenticated attackers …

High 8.1
SurrealDB before 3.1.0 Privilege Escalation via RPC Session Race Condition
SurrealDB versions before 3.1.0 contain a time-of-check/time-of-use race condition in the HTTP /rpc endpoint that allows unauthenticated requests to inherit authenticated session state. Unauthenticated attackers can send concurrent requests to the /rpc endpoi…

High 7.5
SurrealDB before 3.1.0 Denial of Service via malformed RPC use
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.
