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."}],"title":"Ultimate Member <= 2.11.2 - Authenticated (Contributor+) Sensitive Information Exposure to Account Takeover via Shortcode Template Tag","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/baafd001-144d-4ee4-b7e6-28c0931e6e10?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.11.2/includes/um-short-functions.php#L205"},{"url":"https://github.com/ultimatemember/ultimatemember/pull/1799"},{"url":"https://plugins.trac.wordpress.org/changeset/3492178/ultimate-member/trunk/includes/um-short-functions.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-285 Improper Authorization","cweId":"CWE-285","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","baseScore":8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"HDH"}],"timeline":[{"time":"2026-03-16T05:45:39.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-03-27T09:48:30.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-01T13:46:29.470662Z","id":"CVE-2026-4248","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-01T13:50:46.111Z"}}]}}
