This is due to the `permission_callback` only validating wp_rest nonce without checking user capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary subscriber records.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/popup-builder-block/tags/2.2.0/includes/Routes/Subscribers.php#L64","https://plugins.trac.wordpress.org/browser/popup-builder-block/tags/2.2.0/includes/Routes/Subscribers.php#L77","https://plugins.trac.wordpress.org/browser/popup-builder-block/trunk/includes/Routes/Subscribers.php#L77","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3421671%40popup-builder-block&new=3421671%40popup-builder-block&sfp_email=&sfph_mail=","https://www.wordfence.com/threat-intel/vulnerabilities/id/48f5a44d-d01f-4c41-98da-7c1f6c65c254?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2025-14441","score":0.00233,"percentile":0.14223,"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).
