CVE-2026-67357 is an information disclosure vulnerability affecting ArcadeDB versions prior to 26.7.3. The flaw is present in the MCP get_server_settings tool, which exposes the value of the high-availability cluster token in cleartext. An attacker with access to the MCP interface can retrieve this sensitive authentication material and then reuse it in cluster-related request headers to impersonate the root user. Because the disclosed token can be used to satisfy trust assumptions in inter-node or privileged request handling, the issue can lead directly from information disclosure to full server compromise.
