The client writes a system-wide OpenSSH drop-in file (/etc/ssh/ssh_config.d/99-netbird.conf, or the equivalent under %PROGRAMDATA%\\ssh\\ssh_config.d on Windows) that embeds each peer FQDN or hostname inside a double-quoted Match host directive without escaping. A peer name containing a double quote breaks out of the quoted context and injects arbitrary SSH configuration directives, including exec commands, which run locally as any user on the host the next time that user runs ssh. Desktop clients on Linux, macOS, Windows and FreeBSD are affected; the Android and iOS apps are not. The issue is fixed in version 0.74.7, which accepts a peer FQDN or hostname only if it is a valid DNS name.","state":0,"publishedAt":"2026-10-14T04:33:44.856+00:00","modifiedAt":"2026-10-16T15:31:53.347+00:00","affected":[{"ecosystem":"https://pkg.go.dev","name":"github.com/netbirdio/netbird","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"NetBird\",\n                    \"product\": \"NetBird\",\n                    \"collectionURL\": \"https://pkg.go.dev\",\n                    \"packageName\": \"github.com/netbirdio/netbird\",\n                    \"repo\": \"https://github.com/netbirdio/netbird\",\n                    \"modules\": [\n                        \"client/ssh/config\"\n                    ],\n                    \"programFiles\": [\n                        \"client/ssh/config/manager.go\"\n                    ],\n                    \"platforms\": [\n                        \"Linux\",\n                        \"macOS\",\n                        \"Windows\",\n                        \"FreeBSD\"\n                    ],\n                    \"cpes\": [\n                        \"cpe:2.3:a:netbird:netbird:*:*:*:*:*:*:*:*\"\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0.60.0\",\n                            \"lessThan\": \"0.74.7\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":8.9,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","score":8,"severity":"HIGH"}],"references":["https://github.com/netbirdio/netbird/security/advisories/GHSA-xmg2-v32j-x2hf","https://github.com/netbirdio/netbird/pull/6805","https://github.com/netbirdio/netbird/releases/tag/v0.74.7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105429","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105429","identifiers":["CVE-2026-105429"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
