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"}]}}}
