CVE-2026-16328
Last modified
CVE-2026-16328 is a high-severity vulnerability rated 8.6/10 on the CVSS scale. 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.
