From 0.25.0 until 0.27.6, the browser SSH path in warpgate-web-ssh/src/manager.rs handles RCEvent::HostKeyUnknown without the presenting hop identity and instead passes ssh_options.host and ssh_options.port for the final target to KnownHosts::trust. In Prompt and AutoAccept modes, a jump host key can therefore be stored for the target address. A machine later presenting the jump host key at the target address can be accepted as the target, allowing interception of user traffic and a newly issued certificate when certificate authentication is used. The native SSH path is unaffected because it tracks each hop separately. This issue is fixed in version 0.27.6.","state":0,"publishedAt":"2026-09-21T18:53:56.224+00:00","modifiedAt":"2026-09-24T22:32:09.888+00:00","affected":[{"ecosystem":"Vendor product","name":"warpgate","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"warp-tech\",\n                    \"product\": \"warpgate\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.25.0, < 0.27.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:N","score":5.7,"severity":"MEDIUM"}],"references":["https://github.com/warp-tech/warpgate/security/advisories/GHSA-w9jj-vpw3-5r8f","https://github.com/warp-tech/warpgate/commit/fb66ff74f979c22054f4d348cc0d9065cc67e5d3","https://github.com/warp-tech/warpgate/releases/tag/v0.27.6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-91166","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-91166","identifiers":["CVE-2026-91166"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
