{"cve":"CVE-2026-97337","nvd":{"published":"2026-10-03T06:16:48.943","modified":"2026-10-06T15:04:52.637","status":"Deferred","description":"The Simple Membership plugin for WordPress is vulnerable to unauthorized modification of data and sensitive information disclosure in versions up to, and including, 4.8.3 via the resend-activation and email-activation endpoints. The endpoints are dispatched from SwpmInitTimeTasks::check_and_do_email_activation() on frontend init with no authentication, nonce, capability, or ownership check, and the recipient address used by SwpmRegistration::send_reg_email() is taken from an attacker-controlled $_POST['email'] parameter (overriding the member's registered address). This makes it possible for unauthenticated attackers to redirect an arbitrary pending member's activation email — and the follow-up 'registration complete' email containing the member's username and plaintext password — to an attacker-chosen address, and to then activate that member's account without their consent.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.8.3/classes/class.swpm-front-registration.php#L774","https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.8.3/classes/class.swpm-front-registration.php#L850","https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.8.3/classes/class.swpm-init-time-tasks.php#L167","https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.8.3/classes/class.swpm-registration.php#L75","https://plugins.trac.wordpress.org/changeset?reponame=&old=3716437%40simple-membership&new=3716437%40simple-membership"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-97337","score":0.00374,"percentile":0.31059,"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).
