CVE-2026-16328
High
Description
In consul-mcp-server, versions 0.1.0 up to 0.1.3 did not restrict how the Consul backend address was supplied, allowing a connected client to override the server's configured Consul address via a request header. This may allow a malicious client to redirect the server's Consul API traffic to an attacker-controlled endpoint, potentially exfiltrating the Consul token configured on the server. This vulnerability, CVE-2026-16328, is fixed in consul-mcp-server 0.1.4.
