This is due to missing or incorrect nonce validation on the send_backup_codes_email function. This makes it possible for unauthenticated attackers to send emails with arbitrary content to registered users via a forged request granted they can trick a site administrator or other registered user into performing an action such as clicking on a link. While a nonce check is present, it is only executed if a nonce is set. By omitting a nonce from the request, the check can be bypassed.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-352"],"references":["https://plugins.trac.wordpress.org/browser/wp-2fa/trunk/includes/classes/Admin/class-setup-wizard.php?rev=2940688#L606","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3009922%40wp-2fa&new=3009922%40wp-2fa&sfp_email=&sfph_mail=","https://www.wordfence.com/threat-intel/vulnerabilities/id/0af451be-2477-453c-a230-7f3fb804398b?source=cve","https://plugins.trac.wordpress.org/browser/wp-2fa/trunk/includes/classes/Admin/class-setup-wizard.php?rev=2940688#L606","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3009922%40wp-2fa&new=3009922%40wp-2fa&sfp_email=&sfph_mail="],"products":["melapress:wp_2fa"],"source":"nvd","synced_at":"2026-10-19T21:43:38.875533635+00:00"},"epss":{"cve":"CVE-2023-6520","score":0.00246,"percentile":0.15902,"date":"2026-11-01"},"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).
