The handler reads the client-supplied post_id and retrieves the corresponding email log post content (including the password-reset link) without adequately validating the ownership or restricting to administrators. This allows an authenticated attacker with Contributor-level access to obtain an admin\u2019s reset link and elevate their privileges to the administrator level.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-3835205592\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Below is a conceptual example of how the vulnerability might be exploited:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/wp-admin\/admin-ajax.php HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\naction=get_email_log_details&amp;post_id=123<\/code><\/pre>\n<p>In this example, the post_id is supplied by the attacker, which would allow them to retrieve the corresponding email log post content, including the password-reset link for the admin user.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. In the meantime, use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. Regularly updating and patching the Ultimate WP Mail plugin can help prevent exploitation of such vulnerabilities in the future.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report presents a detailed analysis of the CVE-2025-6993 vulnerability that affects the Ultimate WP Mail plugin for WordPress.
