CVE 설명
Arc is an open, SQL-native time-series database for telemetry. Prior to version 26.06.1, Arc Enterprise's cluster replication receiver at `internal/cluster/replication/receiver.go` validates only the wire-format envelope (length, opcode) of inbound messages. The `MsgReplicateSync` payload itself is accepted without any application-layer authentication — no HMAC, no signature, no per-message nonce. The replication stream is protected at the transport layer by TLS / mTLS, but there is no protection against application-layer message tampering or replay once a peer is on the cluster network. This is fixed in 2026.06.1. Some workarounds are available. Restrict cluster network access to known-trusted peers via strict firewall rules, audit replication logs for unexpected `MsgReplicateSync` traffic, and/or disable cluster mode until the fix is available.

관련 약점
| 약점 이름 | 출처 | |
|---|---|---|
| Missing Authentication for Critical Functionality The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. |
||
| Insufficient Verification of Data Authenticity The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data. |
||
| Improper Enforcement of Message Integrity During Transmission in a Communication Channel The product establishes a communication channel with an endpoint and receives a message from that endpoint, but it does not sufficiently ensure that the message was not modified during transmission. |
