Prior to 0.5.2, 9router treats loopback requests as trusted and allows /v1/* access without an API key, so a same-host reverse proxy that forwards public traffic to the backend through 127.0.0.1 causes src/dashboardGuard.js to misclassify external requests as local. A remote unauthenticated attacker can access /v1 APIs such as /v1/models and may abuse configured upstream provider credentials through /v1 proxy endpoints depending on enabled providers. This issue is fixed in version 0.5.2.","state":0,"publishedAt":"2026-07-10T15:39:23.282+00:00","modifiedAt":"2026-07-10T16:55:03.329+00:00","affected":[{"ecosystem":"Vendor product","name":"9router","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"decolua\",\n                    \"product\": \"9router\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.5.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L","score":8.3,"severity":"HIGH"}],"references":["https://github.com/decolua/9router/security/advisories/GHSA-x5c9-v98j-722r","https://github.com/decolua/9router/commit/da667836cc7584bea0edd893de1d590c9ea279dc","https://github.com/decolua/9router/releases/tag/v0.5.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-56675","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-56675","identifiers":["CVE-2026-56675"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
