A remote, unauthenticated attacker can log in with the default credential, spoof the Host header to reach local-only routes, and register a malicious MCP plugin (e.g. node -e ) to achieve arbitrary code execution on the host operating system when the plugin's SSE endpoint is triggered." } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "description": "Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')", "cweId": "CWE-78", "type": "CWE" } ] } ], "affected": [ { "vendor": "decolua", "product": "9router", "defaultStatus": "unaffected", "packageURL": "pkg:npm/9router", "versions": [ { "version": "0", "status": "affected", "versionType": "semver", "lessThan": "0.4.60" }, { "version": "0.4.60", "status": "unaffected", "versionType": "semver" } ] } ], "metrics": [ { "format": "CVSS", "cvssV4_0": { "version": "4.0", "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H", "attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "NONE", "privilegesRequired": "LOW", "userInteraction": "NONE", "vulnConfidentialityImpact": "HIGH", "vulnIntegrityImpact": "HIGH", "vulnAvailabilityImpact": "HIGH", "subConfidentialityImpact": "HIGH", "subIntegrityImpact": "HIGH", "subAvailabilityImpact": "HIGH", "baseScore": 9.4, "baseSeverity": "CRITICAL" } }, { "format": "CVSS", "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 9.9, "baseSeverity": "CRITICAL" } } ], "references": [ { "url": "https://github.com/decolua/9router/security/advisories/GHSA-4922-8r65-fq26", "name": "GitHub Security Advisory (GHSA-4922-8r65-fq26)", "tags": [ "vendor-advisory" ] }, { "name": "VulnCheck Advisory: 9router before 0.4.60 Remote Code Execution via default password", "tags": [ "third-party-advisory" ], "url": "https://www.vulncheck.com/advisories/9router-before-remote-code-execution-via-default-password" } ], "credits": [ { "lang": "en", "value": "darealDanh", "type": "reporter" } ], "x_generator": { "engine": "vulncheck-endgame" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-07-27T16:14:47.859374Z", "id": "CVE-2026-63732", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-07-27T16:19:25.094Z" } } ] } }
