{"cve":"CVE-2025-64443","nvd":{"published":"2025-12-03T18:15:46.670","modified":"2026-10-18T17:10:00.110","status":"Analyzed","description":"MCP Gateway allows easy and secure running and deployment of MCP servers. In versions 0.27.0 and earlier, when MCP Gateway runs in sse or streaming transport mode, it is vulnerable to DNS rebinding. An attacker who can get a victim to visit a malicious website or be served a malicious advertisement can perform browser-based exploitation of MCP servers executing behind the gateway, including manipulating tools or other features exposed by those MCP servers. MCP Gateway is not affected when running in the default stdio mode, which does not listen on network ports. Version 0.28.0 fixes this issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:H/VA:N/SC:H/SI:H/SA:H","score":7.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.6},"cwes":["CWE-749"],"references":["https://github.com/docker/mcp-gateway/commit/6b076b2479d8d1345c50c112119c62978d46858e","https://github.com/docker/mcp-gateway/security/advisories/GHSA-46gc-mwh4-cc5r"],"products":["docker:mcp_gateway"],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-64443","score":0.00425,"percentile":0.36505,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-46gc-mwh4-cc5r","url":"https://osv.dev/vulnerability/GHSA-46gc-mwh4-cc5r","summary":"Docker MCP Plugin and Docker MCP Gateway have DNS Rebinding vulnerability when running in sse or streaming mode","modified":"2025-12-09T17:57:50.930084Z","packages":[{"ecosystem":"Go","name":"github.com/docker/mcp-gateway","purl":"pkg:golang/github.com/docker/mcp-gateway","ranges":["<0.28.0"],"fixed":["0.28.0"]}]},{"id":"GO-2025-4179","url":"https://osv.dev/vulnerability/GO-2025-4179","summary":"Docker MCP Plugin and Docker MCP Gateway have DNS Rebinding vulnerability when running in sse or streaming mode in github.com/docker/mcp-gateway","modified":"2026-03-03T04:57:44.397256Z","packages":[{"ecosystem":"Go","name":"github.com/docker/mcp-gateway","purl":"pkg:golang/github.com/docker/mcp-gateway","ranges":["<0.28.0"],"fixed":["0.28.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
