CVE-2026-16328: Hashicorp Tooling

High severity, CVSS 8.6. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Hashicorp Tooling: from 0.1.0, before 0.1.4 (fixed in 0.1.4)
