{"id":"CVE-2026-16328","summary":"consul-mcp-server vulnerable to server side request forgery leading to token exposure","details":"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.","modified":"2026-08-01T03:33:04.954610847Z","published":"2026-07-29T18:32:39.870Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/16xxx/CVE-2026-16328.json","cna_assigner":"HashiCorp","cwe_ids":["CWE-918"]},"references":[{"type":"WEB","url":"https://discuss.hashicorp.com/t/hcsec-2026-24-multiple-vulnerabilities-impacting-hashicorp-consul-mcp-server/77612"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/16xxx/CVE-2026-16328.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-16328"},{"type":"PACKAGE","url":"https://github.com/hashicorp/consul-mcp-server"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/hashicorp/consul-mcp-server","events":[{"introduced":"0"},{"fixed":"cfc1e4c47dcd5c7a092bddcd1ac2682774906320"}],"database_specific":{"extracted_events":[{"introduced":"0.1.0"},{"fixed":"0.1.4"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.1.3","v0.1.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-16328.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N"}]}
