Man-in-the-middle attackers can present any certificate to intercept or modify gRPC transport, HTTP and RabbitMQ broker, and Consul or etcd registry traffic, including authentication tokens and credentials.","severity":"critical","score":9.1,"published":"2026-10-04T17:09:52.327Z","modified":"2026-10-27T01:30:38.154Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/micro/go-micro/issues/2963","https://github.com/micro/go-micro/commit/c7657f73f45cf839e643db10f28703eeab7299c3","https://github.com/micro/go-micro/blob/v5.30.0/internal/util/tls/tls.go#L43-L67","https://github.com/micro/go-micro","https://www.vulncheck.com/advisories/go-micro-before-6.0.0-disabled-tls-certificate-verification-via-tls-config-helper"],"sources":[{"name":"CVE","id":"CVE-2026-105216","modified":"2026-10-27T01:30:38.154Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-105216"}],"assessments":[{"source":"VulnCheck","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":9.1},{"source":"VulnCheck","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T23:20:36.067Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
