{"id":"CVE-2026-4248","state":"PUBLISHED","title":"Ultimate Member <= 2.11.2 - Authenticated (Contributor+) Sensitive Information Exposure to Account Takeover via Shortcode Template Tag","description":"The Ultimate Member plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.11.2. This is due to the '{usermeta:password_reset_link}' template tag being processed within post content via the '[um_loggedin]' shortcode, which generates a valid password reset token for the currently logged-in user viewing the page. This makes it possible for authenticated attackers, with Contributor-level access and above, to craft a malicious pending post that, when previewed by an Administrator, generates a password reset token for the Administrator and exfiltrates it to an attacker-controlled server, leading to full account takeover.","publishedAt":"2026-03-27T22:26:22.535Z","updatedAt":"2026-04-08T17:18:18.777Z","severity":{"score":8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["ultimatemember Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin"],"affected":[{"vendor":"ultimatemember","product":"Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.11.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/baafd001-144d-4ee4-b7e6-28c0931e6e10?source=cve","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.11.2/includes/um-short-functions.php#L205","https://github.com/ultimatemember/ultimatemember/pull/1799","https://plugins.trac.wordpress.org/changeset/3492178/ultimate-member/trunk/includes/um-short-functions.php"],"weaknesses":["CWE-285"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4248.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4248","state":"PUBLISHED","datePublished":"2026-03-27T22:26:22.535Z","dateUpdated":"2026-04-08T17:18:18.777Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-16T05:30:05.899Z"},"containers":{"cna":{"title":"Ultimate Member <= 2.11.2 - Authenticated (Contributor+) Sensitive Information Exposure to Account Takeover via Shortcode Template Tag","descriptions":[{"lang":"en","value":"The Ultimate Member plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.11.2.
