{"cve":"CVE-2026-7647","nvd":{"published":"2026-05-02T06:16:04.803","modified":"2026-06-17T11:02:43.993","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-502"],"references":["https://plugins.trac.wordpress.org/browser/profile-builder-pro/tags/3.14.5/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#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/trunk/add-ons/user-listing/one-map-listing.php#L271","https://www.wordfence.com/threat-intel/vulnerabilities/id/c7b897f5-f988-4515-83bc-456f041d7e2e?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-7647","score":0.00462,"percentile":0.40097,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
