This is due to the use of a predictable low-entropy token (5 hex characters derived from md5 of post ID) to identify member directories and insufficient authorization checks on the unauthenticated AJAX endpoint. This makes it possible for unauthenticated attackers to extract sensitive data including usernames, display names, user roles (including administrator accounts), profile URLs, and user IDs by enumerating predictable directory_id values or brute-forcing the small 16^5 token space.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-200"],"references":["https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.10.6/includes/class-functions.php#L41","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.10.6/includes/core/class-ajax-common.php#L61","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.10.6/includes/core/class-member-directory.php#L205","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.10.6/includes/core/class-member-directory.php#L2795","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.10.6/templates/members.php#L26"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2025-12492","score":0.0052,"percentile":0.44199,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
