{"id":"CVE-2026-1994","state":"PUBLISHED","title":"s2Member <= 260127 - Unauthenticated Privilege Escalation via Account Takeover","description":"The s2Member plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 260127. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.","publishedAt":"2026-02-19T06:49:43.503Z","updatedAt":"2026-04-08T16:59:09.633Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["clavaque s2Member – Excellent for All Kinds of Memberships, Content Restriction Paywalls & Member Access Subscriptions"],"affected":[{"vendor":"clavaque","product":"s2Member – Excellent for All Kinds of Memberships, Content Restriction Paywalls & Member Access Subscriptions","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"260127","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/6c31cf92-26b7-484d-8c93-ce241d655d07?source=cve","https://plugins.trac.wordpress.org/browser/s2member/tags/260127/src/includes/classes/registrations.inc.php#L74","https://plugins.trac.wordpress.org/changeset/3461625/s2member#file5"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1994.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1994","state":"PUBLISHED","datePublished":"2026-02-19T06:49:43.503Z","dateUpdated":"2026-04-08T16:59:09.633Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-05T16:34:36.592Z"},"containers":{"cna":{"title":"s2Member <= 260127 - Unauthenticated Privilege Escalation via Account Takeover","descriptions":[{"lang":"en","value":"The s2Member plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 260127.
