This is due to the plugin exposing a public AJAX endpoint that allows anyone to search for and retrieve user email addresses without any authentication or capability checks. This makes it possible for unauthenticated attackers to enumerate user accounts and extract email addresses via the guest_support_handler=ajax endpoint with the request=get_users parameter.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-200"],"references":["https://plugins.trac.wordpress.org/browser/guest-support/tags/1.2.3/includes/library/ajax.php#L22","https://plugins.trac.wordpress.org/browser/guest-support/trunk/includes/library/ajax.php#L22","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3412822%40guest-support&new=3412822%40guest-support&sfp_email=&sfph_mail=","https://www.wordfence.com/threat-intel/vulnerabilities/id/01299aba-0dff-47fd-9e90-ee84f00a0f3b?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-13660","score":0.0033,"percentile":0.25886,"date":"2026-10-25"},"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).
