{"schemaVersion":3,"id":"CVE-2026-97337","aliases":[],"status":"published","duplicateOf":null,"title":null,"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.","dates":{"published":"2026-10-03T05:29:16.871Z","modified":"2026-10-03T15:42:44.331Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"wordfence","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00374,"percentile":0.29903,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-03T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00374,"percentile":0.29903}],"last30":[{"date":"2026-10-03T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00374,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00374,"percentile":0.29903}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-862","name":"Missing
