This is due to a chain of three logic bugs: (1) an MD5 hash fallback in get_directory_by_hash() that allows any post to be used as a member directory by computing SUBSTRING(MD5(post_id), 11, 5), (2) a strstr() parsing logic flaw in post_data() that allows bypassing WordPress's protected meta key restrictions by placing '_um_' anywhere in the meta key name rather than at the start, and (3) missing field name validation in build_user_card_data() that allows arbitrary field names including 'password_reset_link' to be passed to um_filtered_value(). This makes it possible for authenticated attackers with Contributor-level access and above to create a malicious post via XMLRPC with crafted meta fields, use the MD5 fallback to point the member directory AJAX handler to their post, inject 'password_reset_link' into the tagline_fields configuration, and leak live password reset URLs for all users in the member directory response, including administrators."}],"title":"Ultimate Member <= 2.11.4 - Authenticated (Contributor+) Account Takeover via Password Reset Link Disclosure","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/9aff7b03-4f03-434c-be87-b10ceeb4e625?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/trunk/includes/core/class-member-directory.php#L2726"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.11.4/includes/core/class-member-directory.php#L2726"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/trunk/includes/core/class-member-directory.php#L289"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.11.4/includes/core/class-member-directory.php#L289"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/trunk/includes/core/class-query.php#L439"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.11.4/includes/core/class-query.php#L439"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/trunk/includes/um-short-functions.php#L2611"},{"url":"https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.11.4/includes/um-short-functions.php#L2611"},{"url":"https://plugins.trac.wordpress.org/changeset/3569970/"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Kevin Wydler"}],"timeline":[{"time":"2026-05-04T04:12:16.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-06-23T00:00:00.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-24T19:57:32.944884Z","id":"CVE-2026-7761","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":"2026-06-24T19:57:44.569Z"}}]}}
