{"id":"CVE-2026-7647","state":"PUBLISHED","title":"Profile Builder Pro <= 3.14.5 - Unauthenticated PHP Object Injection","description":"The Profile Builder Pro plugin for WordPress is vulnerable to PHP Object Injection in all versions up to and including 3.14.5. 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.","publishedAt":"2026-05-02T05:29:30.319Z","updatedAt":"2026-05-04T12:48:13.345Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["Cozmoslabs Profile Builder Pro"],"affected":[{"vendor":"Cozmoslabs","product":"Profile Builder Pro","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.14.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/c7b897f5-f988-4515-83bc-456f041d7e2e?source=cve","https://plugins.trac.wordpress.org/browser/profile-builder-pro/trunk/add-ons/user-listing/one-map-listing.php#L271","https://plugins.trac.wordpress.org/browser/profile-builder-pro/tags/3.14.5/add-ons/user-listing/one-map-listing.php#L271","https://plugins.trac.wordpress.org/browser/profile-builder-pro/trunk/add-ons/user-listing/one-map-listing.php#L13","https://plugins.trac.wordpress.org/browser/profile-builder-pro/tags/3.14.5/add-ons/user-listing/one-map-listing.php#L13"],"weaknesses":["CWE-502"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/7xxx/CVE-2026-7647.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-7647","state":"PUBLISHED","datePublished":"2026-05-02T05:29:30.319Z","dateUpdated":"2026-05-04T12:48:13.345Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-01T17:10:21.145Z"},"containers":{"cna":{"title":"Profile Builder Pro <= 3.14.5 - Unauthenticated PHP Object Injection","descriptions":[{"lang":"en","value":"The Profile Builder Pro plugin for WordPress is vulnerable to PHP Object Injection in all versions up to and including 3.14.5.
