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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"decolua","product":"9router","versions":[{"version":"< 0.5.2","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L","baseScore":8.3,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":3.7}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-07-10T16:54:55.352353Z","id":"CVE-2026-56675","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-287"},{"lang":"en","value":"CWE-290"},{"lang":"en","value":"CWE-306"},{"lang":"en","value":"CWE-441"}]}],"references":[{"url":"https://github.com/decolua/9router/commit/da667836cc7584bea0edd893de1d590c9ea279dc","source":"security-advisories@github.com"},{"url":"https://github.com/decolua/9router/releases/tag/v0.5.2","source":"security-advisories@github.com"},{"url":"https://github.com/decolua/9router/security/advisories/GHSA-x5c9-v98j-722r","source":"security-advisories@github.com"}]}
