• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2025-07-16 · updated 2026-06-17
• Weakness: CWE-862

Description

The Ultimate WP Mail plugin for WordPress is vulnerable to Privilege Escalation due to improper authorization within the get_email_log_details() AJAX handler in versions 1.0.17 to 1.3.6. The handler reads the client-supplied post_id and retrieves the corresponding email log post content (including the password-reset link), relying only on the ‘edit_posts’ capability without restricting to administrators or validating ownership. This makes it possible for authenticated attackers, with Contributor-level access and above, to harvest an admin’s reset link and elevate their privileges to administrator.

Affected products

• Rustaurius Ultimate WP Mail: from 1.0.17 before 1.3.7 — fixed in 1.3.7

How to fix

Upgrade to a fixed version: Rustaurius Ultimate WP Mail 1.3.7. Check the vendor advisory for mitigations.
