CVE-2026-16328

In consul-mcp-server, versions 0.1.0–0.1.3 did not restrict how the Consul backend address was supplied, allowing a connected client to override the server’s Consul address via a request header. This could redirect the server’s Consul API traffic to an attacker-controlled endpoint and potentially...
